I've been asked how to decode the chassis numbers on the 914/6. Not the VIN's, but the Karmann body number. If I recall, the number is not on the paint code plate as is the case with the 914/4. There are two places I can think of where it could be found. The easiest is in the rear trunk floor in front of the lock. About 1/2" high characters. If someone can post a picture of it, that would really help. I need to correlate VIN's with the chassis numbers. If the paint code is included that would also be useful. The other location for the chassis number is on the bottom of the dash; at least with the 914/4, not sure about the six. I need as many sets of data as possible to be able to work this out. Results will be posted in the '914 Info' section when completed. Thanks for your help.
DaveP
Heppy to look.
Didn't see anything in the trunk -- however, I just looked by the lock. I'll empty it this afternoon and look more closely.
Where under the dash would you expect to find it? (i.e. do I have to remove something?) How big would it be? (i.e. I took a quick look and didn't see anything)

Paint 15 (Irish Green)
Chassis # is about 3" forward from the latch mechanism

Excellent, just exactly what I need. Thanks for the photo. It sure is not the same scheme as the /4.
If it is under the dash, then it is on the bottom side of the metal dash top, just about the ashtray. About 2" characters, be careful, the German 1 looks like a 7, and the 7 has a cross like a t. Handwritten with a crayon or magic marker.
DaveP
I was just checking some old info, and it may be that the number on the underside of the dash is different from the trunk floor number. So, if you can stand on your head, please check to see what you can find there. As you can see from the picture, the 914/6 chassis number is one digit less than the 914/4 chassis number.
DaveP
That may be true, but I can say that the 914/4 dashes have the same number on the bottom as the chassis has, so they certainly seem to be matched.
DaveP
Speaking of dashboard frames... on both my cars they are light blue metalic
First I thought they just got "any painted" one off the rack, but then how big would the chance be that both of my cars have light blue metalic ones???
cheers,
Jeroen
I remember thinking about this years ago, and perhaps they just sprayed them with whatever leftover paint they had. It would have been just to prevent instant rusting, so the color did not matter.
DaveP
Paint code 14 is signal orange. With your data point I am starting to see a pattern, but the VIN's are a bit too close together to be sure of anything yet.
DaveP
DaveP,
I got some original snapshots from the PO -- and I think he probably got them from the PPO. It was definitely orange. (it's a pretty good respray, but not perfect)
On a different note ("oh look, a moose") Brad and I spent an afternoon studying two cars, and there was quite a bit of info he was mumbling that I'd not heard before. (The seam sealer in the trunk is different between the /4's and /6's -- I can't describe it as we were looking at two /6's -- but apparently they are different -- which led to a discussion of the differences in the manufacturing techniques and practices that might differ)
So the thinking that afternoon revolved around practices that work in volume and those that don't. Porsche only made ~3K /6's, while the number of /4's is numbered in the100'sK range.
When a manufacturing process doesn't scale up, it is replaced by one that does. Manual processes are replaced by machine processes.
We looked at the VIN plate from a /6 and one from a /4. The /6 has a (originally) black faced one that looks a lot like a 911 VIN from the same period. (surprise) They look like they could have been cut with tin snips and bent on a brace. The /4 vin's have a rolled edge and look a little more professionally manufactured.
I'm babbling a bit, but you get the idea. Limited runs of low numbers can live with labor intensive processes which will change when scaling up.
I'll take a look in daylight under the dash and see if there's anything w/numbers. I'll be quite interested to hear what you discover!
kim.
Kim,
One thing I noticed was that the 914/6 had flat black paint (or something) on the top of the shock towers in the front trunk. It is just aft of the gas tank bulkhead. I'm not sure how far down it goes. Anyone have a picture of this to illustrate my point? This contrasted with the body color, so it stood out. A repaint would surely hide this, but I found it any easy way of detecting an original six quickly. The next question is why they did this, and I have no explanation.
DaveP
Dave,
Yeh, Brad did mention that as we were rummaging -- I think he mentioned that it made color changing a little easier :-)
kim.
Sure enough, never noticed but my 4 is all body color around the strut mount.

Jim,
Actually, that's different than I was thinking. Thanks for the pic!
kim.
I'm not sure why it makes a color change easier. Is it more like undercoating than paint? Thanks for the pic.
We'll have to get Brad in on this thread. I have so little access to 914's up here. Almost no 914/6 came to Canada except for owner imports. I need to get out more, and head south while I'm at it.
We've had a thunderstorm tonight, and we're expecting significant snow by morning. Ah well, spring is on its way.... eventually...I hope.
DaveP
Dave,
I'm guessing it was a tongueincheek sort of comment.
(btw, I lived in TO for a zillion years, and grew up in MJ -- spring is really close! (yeh, right))

First off.. I love the sixes and wish I could afford Jims green machine.
The color change comment was a joke... everyone knows I hate color change cars.
B
Ah, I understand completely. I have about 10 engine lids, and I think all of them have suffered a color change. The owners should have just traded cars. Doing a correct color change would be extremely expensive.
I need to get more 1971 and some 1972 data to fully make sense of the data. Anyone know of any '72 cars around?
DaveP
hi folks,
concerning the chassis number I found a description in my archive (someone posted this on the PP board) :
first two digits : week of the year the chassis was produced
third digit : day of the week 1,2,3,4,5 ( monday , tuesday, wednesday, thursday, friday)
fourth digit : should always 9 (factory where the chassis was build) to my knowlegde there was only one factory (osnabrück, karmann)
digitis 5,6,7: runnning serial number of the chassis production for one week
Using the VIN and the chassis number you're able to detemine the birtday of your car.
benno
Benno,
That decoding was what I figured out 20 years ago for the 4 cylinder. The sixes have a different code, hence my request for data from the sixes. As you can see from the posts, the six has a 6 digit chassis number, the four has a 7 digit chassis number. In actual fact, the VW's use the same or similar system as the 914/4; my 411 did anyway. The Mittlemotor site has a different, and I think flawed, interpretation.
For the /4, the base code was 9500 up to about Sept 74 then changed to a base of 9000. To this was added the sequence number during the DAY not the week. Thus 9630 would be the 130th chassis that day.
DaveP
Some 911 bodies were built by Karmann. I don't have the way to decode in front of me, but part of a 911 serial number says were it was built
Just a reminder to those having an original, and not responding yet, that I still need more data. In particular, I need data from 71 and 72. I have half of it figured out I believe, but the first part of the code still eludes me.
Does anyone have a link to the site listing all the sixes spotted in the US including sale postings? I seem to have lost it through a few computer changes.
Thanks to all who have assisted in this project.
DaveP
See last post. Still need more data to be sure. There has to be more than a couple of cars owned by club members. Don't be shy, I don't bite.

Kim,
Thanks but there's a lot of them out there in better shape than mine.
I got it out last weekend, drove it for a while then cleaned it up and put it back in mothballs. It runs pretty well but could use a little care in a few places. When I get the other stall in the garage cleaned out the 914 will come back home again. Unfortunately, making space in the garage means building a new tool shed or leaving the wheelbarrow out in the rain. hmmmm. Not a bad idea.
C
Carl,
Thanks for the info. This is the latest 70 model in the list. It sure is a pretty car as Kim says.
Anyone have a 71 model to help me out?
DaveP
BTW, I found a 914-8 photo that shows the one-piece

DaveP,
Also, you may have seen this already but the pca website has a list of 914-6 owners and their e-mail addresses. You might be able to contact these people for more information. Some of them are 1971 owners. One person is even a 1974 owner (I'm not quite sure how that happened). Try this link:
http://www.pca.org/914/SIGsiteRegisters6.html
Douglas
Kind of a short list...
I think I know that many people with sixes in the bay area...
B
Okay Brad, you're on. Lets see the data you can collect from them.
Any data you can collect will be appreciated. I'd be particularly interested in 9140430004 since that will definitely be a 69 chassis, and there are not many of them. Now, I'm not asking you to run out just to check that out for me. Just remember me the next time you get the chance.
DaveP
Number 4 is about 6 hours south of me right now..
What would you like to know about it ??
B
Just the usual Brad. VIN, chassis #, paint code, DOT decal data, and eventually the engine and trans data. No hurry, that would take a whole day round trip. In fact, that car may have a long list of differences from regular production that would be interesting to document. I'm itching to learn more, but have learned to be patient and not to push my luck.
DaveP
I documented 80% of the car in a thread here when I first shot pics detailing the major differences between it and a regular 9146.
Mike Mueller started the thread for me... I posted pics when I returned. Its a full blown prototype.

Here you go Dave..

B
Info removed for security reasons. I'd be happy to provide it again to Dave directly if necessary.
That looks like #356 not #256? Am I missing something?
Jeff
Here is another one I found buried behind a house...
B
Brad, can you get the chassis number from 2617 or any other sixes that pass through please.
Doug, the paint code should be on the Karmann plate and it should be "80".
The 914 SIG list is by 6 cylinders, so they include conversions there as well, hence the 74's.
I'll try to email a few more people, I just hate to bug anyone on this.
Okay, the results so far seem to suggest that the chassis number for 1970 began with 13 followed by are sequence number that roughly follows the VIN. Both the chassis number and the VIN have a 4 digit sequence number, so it seems reasonable. What the 13 stands for I cannot guess. I have only one very old data point for 71, and I wrote down 31 as the starting digits. Unlike the /4 chassis that had daily sequence numbers it appears the /6 used an annual sequence number. There sure is a lot of bouncing around though; i.e. they do not track closely.
Thanks to everyone that has supplied data. Please keep it coming so that we can learn more. I'd like to write this up for the INFO section so that everyone can benefit.
DaveP
Okay Rich, I'll forgive your tardiness if you share your secret of tequila and lime juice marinade. I just happen to have some Mexican tequila waiting to be put into action. That bottle has a story of its own to tell.

davep,
Some of us with 914-6s apparently have no chassis numbers. The chassis plate is blank and the trunk floor is not stamped. I think you asked for '71 and '72 cars in particular. Here is my certificate of authenticity for my '71:

So here's my trunk floor. I don't think that coat of paint is so thick that it obliterated the numbers.
Attached image(s)
Doug, I'll believe you, it is strange but not surprising.
Marc, try looking to the right in front of the taillight where the /4 chassis number is stamped.
Rusty could not find a number in his trunk either, again strange but not surprising.
Karl, what is your VIN? That is a good photo. Mine were so faint as to be nearly invisible. I don't recall seeing another number on the dashes. Where is it located? No idea what it may signify.
DaveP
Isn't 43 the plant code?
If it is, it won't be found on a /6?
M
I'm not too sure about plant codes. If anyone has any info on this, I'd love to hear about it.
DaveP
okay - went to storage today to extract the alternator pulley (only half of which i could get, and it was quite the b!tch).
VIN - 9140432567
Chassis - 132 330
Karmann # - blank
paint code - 29 - 'Canary Yellow'
I don't know?
Olav, don't know what?
Just got a note from a 71 owner. In his car the chassis number is stamped in front of the right taillight as are the 914/4. They went to 7 digits to accomodate the new model year. thus the 13 became 131 followed by the sequence number. More info to follow. Any more owners want to contribute? Thanks.
DaveP
Okay, found the chassis numbers by the right taillight and under the dash. Here's a partial of the underside of the dash (trying to take pictures in the dark meant I didn't quite frame it right):
Attached thumbnail(s)
and here's the number stamped in the floor of my 1971 914/6. Did all 914s switch the trunk-stamped numbers from the center to the taillight area in 1971? I have a 1970 914/4 with the number stamped in the center rear.
By the way, this number is 1310204.
Attached thumbnail(s)
Thanks Marc. It is interesting to note that the chassis # and the VIN are very close, and the dash is in sync with the chassis. Do you have the DOT decal showing the month/year of production?
You may be correct on the location change of chassis # from 1970 to 1971. Come to think of it, I've never seen chassis # in a 1970 914/4 only 1970 914/6. Could you provide the photo for the 70 914/4 chassis number please.
DaveP
Yep, got the decal. Guess the car just celebrated its 33rd birthday.
Actually, I don't know if "celebrate" is the correct word considering the condition it's currently in.

So, it was built in 2/71.
Here's where the chassis number sits in my 1970 914/4:

I don't know if Dave's still interested in this, but I'm going to bump it because of all our new members. Maybe more sixers can add their info.
Olav might be able to add his VIN and paint code, but I know his chassis number is 131981. VERY close to Jim Chambers car. Olav's chassis had some ODD sheet metal in the front trunk. Definitely different than the other cars I've seen six, or four.

What odd sheetmetal??? I don't recall it course I saw it two years ago. |
Here's the numbers for the six in my shop.
Chassis: 130914
VIN: 9140431232
Color: ????? It's been acid dipped and the number's missing. I'm looking at the old pics trying to see if I can decipher it.
Here's a picture showing the differences in olav's car. The purple arrows are the holes which are not cut out, and the orange box is the bumps. Olav's bumps extend towards the center of the car about 1" to 1.5" more than those. He also doens't have the welded in nut that you bolt the horn to. I've contacted Jim Chambers, because if you look at his post in this thread, he's got chassis number 131984. The car produced 3 cars after Olav's.

If you are doing this again:
VIN: 9140432432
Chas: 1 3250 4
Karmann:
Paint: 80
Great, keep them coming.
Chassis 130914 is way out of sync with the VIN 9140431232. The 914 and 1232 should be closer. Maybe due to the paint code (I have 16 Adriatic blue) being scarce and they had the chassis sitting around for a long time before final assembly.
On Olav's car, would it be possible that the car got a new nose? It may be a replacement panel for a 1975; IIRC they did not have the holes punched, and they had other changes for the bumper shocks. BTW Signal orange would be paint code 14, why 47?
Jim Chambers car was 8 past Olavs, but the chassis is only 3 past it. Nitpicking sure, but that is the difference between VIN and chassis #'s. The bodies were welded up and chassis # stamped, then painted. Then they were trimmed up and transported from Karmann to Porsche. At Porsche, the trimmed bodies would be put on the final assembly line when that color was needed. The drive train and suspension would be installed, then the VIN was assigned. Note that the front fender VIN is stamped into an unpainted area; probably left that way to avoid cracking the paint.

Andy, do you have full size versions of those pics you can send me?
As for Olav's front panel being a 76, I checked the 75 in the shop and while the bump shapes are similar, the holes for the bumper shocks would have been obvious and clearly weren't welded shut. The only explaination I can think of along those lines is that it could be a factory replacement panel from 75/76 that came without all the holes punched and without all the nuts welded into place. And actually, the location where Olav has mounted his horn looks to be in the same location as the welded nut on the 75 car I looked at. Meaning the panel may have come without the nuts welded and the body shop just left them off or didn't know to weld them on.

It has black shock towers, holes and small humps
Thanks Jack, 131146 would most likely be correct. The last four digits of the VIN and the chassis # should be close to one another.
I think Olav's front panel is a replacement. My trunk is like Olav's and it has definately been replaced. Big bumps, holes are not cut, and I have bolts to hold my horns in place. This is on VIN 4732924146. The front panel and right front fender appear to have been replaced together. When I had the car stripped my dad said the inner surfaces of the fender looked like the body panels they got at the Porsche dealers he worked for in the late 70's. Hopefully my picture will be attached.

Well I'm convinced. The mystery is solved. Unfortunate outcome, I suppose. One of those things you probably wish you didn't know. But, replacement front panel or not, Olav's car is still amazing and one of my favorite 914s.
I don't see how it's unfortunate, unless you are really hung up on originality. I mean we are talking about 30 year old cars.
Kelly
I'll have to have a look at it closer because I certainly didn't notice any work on it. It looks like a good job if that's what happened though.
And no one else has noticed either.
Hmmmm...
Doesn't bother me either way though because it's still a great car.

It sounds pretty good actually. If the repair is so good as to be almost undetectable except for the different part, I'd be really happy. So, not perfect, such is life. You still have a great car.

Many years ago, but post 1976, a friend had a replacement front panel and it had no holes. Ever since then I have equated no holes to a repair panel. The last panels made had the 75 style profile, so that is what you have.
Now this panel has the holes, and the bolt holes for the early style mount, so it may be an early replacement panel.
