Recently brought to my attention when I collected my parts from the shop back east, I mistakenly got a 4 cylinder crossmember back, not my correct 6 cylinder crossmember. That led me to learn, (thanks Jim, aka Banananose) how to differentiate the two. Here you go:

This is a 4 cylinder crossmember:

This is a correct 6 cylinder crossmember:

I hope that helps in the future.

one learns something every day, never noticed the difference. Thanks for sharing. Just went out and looked at a six and a four. Sure enough

I disagree.

I thought all the early adjusters used allen heads. It would be interesting to see what the part number is on the crossmember.

Do they have a part number stamped on the crossmember?

Another thing, I'll get a better pic, but the adjuster screws just have an 8mm hex section welded onto the threaded section.

Might have been a regular bolt at one time

Should have 911 type support (with flat side) and early allen head adjuster

Also I have found the early steering rack on all my 1970 914/6s (no data on 1971 & 72)

All I know is I bought this car in '99 from a guy who had it since '74, and lots of
records and kept old parts. Highly doubtful that it was changed.

Someone was in there to modify those bolts. 25 years is a long time.

I have seen them all the ways shown. I maintain it was what they had on the shelf that week. The square end cross member looks to be 901 341 013.02. According to the PET 69-73 911 and all 914 share the same cross member 901 341 013 03. Version 01 was for the 64-68 cars.

Mine has the same as yours. My car is vin #9140430275, I see from the vin# list that your vin is 33 down from mine, I wonder if that has anything to do with which type was used? Of course over over 48 years who knows what might have been changed and why.

I would be interested to know if you have 914/4 a-arms as well?
Do you both have 914/6 Boge strut towers?

I was wondering that too. 914-4 torsion bars? or not.

My parts catalog shows:
914-4 = 914 341 013 03
914-6 = 901 341 013 03
911 with shock absorber struts is 901 341 013 03 (1970-71)
911 with shock absorber struts is 911 341 013 05 (1972-73)
911 with spring struts is 901 341 013 03

as I recall the pre 1969 911 suspension was a totally different animal

I have Boge struts and 911-splined arms.

I know the torsion bars are different splines than on my 4 cylinder cars. If it has 6 front brakes then it has 6 struts, no? My car is completely disassembled, I will check next time I am over at my garage.

If it has 6 front brakes then it has 6 struts - correct. Original color would be grey.

-6 struts
914.431.092.00
914.431.093.00

The 914-6 cross member with flat ends, and the front and rear torsion bar carriers all have a P in the Triangle stamp indicating a Porsche part.

The 914-4 cross member and torsion bar carriers all have VW stamps.

A part's presence in a 48 year old car does not prove anything.

Porsche would not have had the 914-4 parts on their shelf. A lot can happen in the first 3 years of ownership. It would not surprise me if someone hit a curb hard and bend the control arm and screwed up the crossmember. The VW part is totally compatible, so sourcing one from a junk yard would have been the obvious move in 1970-1973.

Anybody notice in the recent thread on 9140430355 that it too has the 'wrong'
crossmember?

yes but the correct adjuster bolt..need to know spline count on torsion bars/ control arm...
I have 390, 094 , 854 ? , 1853, all have the correct parts

once upon a time we all "used" these cars

and some of us converted "real sixes" to later 911 crossmembers ! (even alu)

- performance goals sometimes outweigh museum-quality objectives

It also looks like the adjusters were allen socket that had a piece of hex welded in it and cut off to leave a hex stud

WHY BOTHER?

ya think "they" tho't it makes the car more valuable > or what?

Less bother than waiting for the replacement part
Expedient 'repair' of a striped Allen socket adjuster.
