Getting real close to getting her back on the road after hell hole repair, tranny rebuild, oil leak elimination (dang, almost got em all..) and now I'm thinking about the winter project being (or not) swapping to earlier bumpers.

I have a nice set in the garage, I just need lights and grilles.

Am I to do either? Of course there's other reasons why I qualify, but we'll stick with the bumpers fer now...

Thanks

Try this. Take a hammer and hold it by the handel and swing it back and forth useing only your wrist. Now turn the hammer around and swing it by the head.
Your front and rear bumpers weigh more than 50 pounds each. The rear one weighs more than both the front and rear with valances and all related hardware and spoilers.

Think about this: lots of people get rid of their BUBS, but have you ever heard of someone 'updating' to those government imposed protuberances?

Posted by: The Cabinetmaker Aug 11 2013, 07:31 AM

After my 2056 with raby cam, back dating
my bumpers is the best thing I ever did to my 75.
All that extra weight is at the worst possible place it could be.
The corners. Handling difference is night and day.
I have never regretted making this change.

I'll weigh in on this. I have both, a '73 and a '76. The '76 is a dream on the hi way. Is it the weight or aerodynamics? I don't know but there is a noticeable difference! Scientific results? Hardly. Just mine.

Posted by: mepstein Aug 11 2013, 07:48 AM

The front weighs 38lbs, the rear 42lbs. I'm pretty sure the early bumpers weigh ~12lbs each. I do like the look of early bumpers.

Posted by: Cairo94507 Aug 11 2013, 08:09 AM

For me, if I had a late model teener the BUBs would come off immediately and I would never look back.

Posted by: eyesright Aug 11 2013, 08:23 AM

I swapped my '76 bumpers for early ones just for looks. I got some sorry early bumpers from a junk yard. I had one new front bumper top and one nasty rear one they gladly GAVE me while laughing, from the junk yard. It was a lot of work and the bumper repair and paint wasn't cheap (body shop) and a real chore to repair the rear topper (me).

I did a lot of sweating and cussing, but after it was all done....I like it. Come to thnk of it, I think I can recognise the difference in feel on the highway. Maybe the heavy ones did feel better at 75 mph, really. But I do like the looks now.

Maybe I'll put 50 lbs of tools in each trunk when I travel.

Anybody need a very good condition set of late bumpers, covers, and hardware? Free for PU.

Posted by: Porschef Aug 11 2013, 08:45 AM

Hmmm, all good food for thought. That's not the first time I've read that the BUBs seem to improve the ride at highway speeds.

Not that highway speeds are common here on Long Island....

Posted by: damesandhotrods Aug 11 2013, 10:01 AM

If you park in parallel parking spaces regularly, then keep the late bumpers might not be such a bad idea. It never ceases to amaze me how many people parallel park by braille…

Posted by: speed metal army Aug 11 2013, 10:51 AM

The late ones are actual bumpers.. The earlies seem to be nice beauty covers.
I think about it too, but the slightest little tag and the early ones are boned.

Posted by: Krieger Aug 11 2013, 11:24 AM

I like both. I have a 72 and 75. 50 lbs to each end is not the end of the world. Not even close. Joe's hammer analogy is great for understanding the concept, but quite extreme. How much weight is in the head vs the handle? That would be like adding at least 500# to the rear of a 911? When I autocross my 75 I make a lot of cars look really bad. If you have nice late bumpers and like the look use them. It will cost you a lot for nice chrome bumpers and there tops. The 75 -76 cars have tabs welded to the body to hold the sides of the rubber on bumpers. I don't know if people are grinding these off or leaving them.

Edit: oops saw w you already had a pair of chrome bumpers.

Posted by: Joe Sharp Aug 11 2013, 11:47 AM

Here is the scales with the bumpers on them. I did this to be sure of the actual weight going on to the race car. I was thinking about foot pounds and how far the bumpers were form the center of gravity.

Apperently at one time I was into this stuff.

Posted by: mepstein Aug 11 2013, 11:54 AM

You are right. I forgot about the heavy bumper mounts

Posted by: Joe Sharp Aug 11 2013, 12:28 PM

It was not my intention to make anybody wrong. I just remembered weighing all the parts of the cars. I thought the rears were 56 pounds. In foot pounds thats about 300 foot pounds just for the rears on a race car.

Posted by: r_towle Aug 11 2013, 02:53 PM

Get it on the road and drive it....finally.

Do the bumpers later, it will cause you to do paint work.

Rich

Posted by: Dave_Darling Aug 11 2013, 10:27 PM

There are a number of people who like the way the late bumpers look. They do make for a slightly more "finished" look to me. But I know that they imply more weight at the ends of the car, and I think I like the look of the early bumpers because I "know" they're lighter.

I agree with Towelie. Drive it, worry about the bumpers later. You have to cut the lips off the car, which means some paint to protect the metal. Which can very easily lead to body work, fixing prior repairs, a complete repaint, disassembling the whole car to do it, and on and on and on... Just get it together and drive it!

Posted by: Porschef Aug 12 2013, 08:30 AM

Either way, my plan is to get her back on the road this week.

I did mention that it was a winter project...

Thanks to all who took the time to reply. I guess I got a little more thinkin to do

Posted by: balljoint Aug 12 2013, 12:57 PM

Has anyone just gutted the late bumpers to lose the weight but retain the appearance?

Posted by: green914 Aug 12 2013, 03:36 PM

Do It! If for no other reason ... the chrome bumpers just look more cool.

Posted by: jimkelly Aug 12 2013, 04:01 PM

Posted by: okieflyr Aug 12 2013, 04:36 PM

What is the long term plan for the car? Is it still all stock or past the point of return in terms of mods?
Like most I'm not a fan of the BUB's but I have seen some original cars that they did look good on and it may have been because of body color combo.

Posted by: r_towle Aug 12 2013, 04:42 PM

Yup, hole saw, jig saw,,,just enough left to hold the rubber in place.

Rich

Posted by: Drums66 Aug 12 2013, 04:44 PM

......I like them...do what you like!
On a street car, I can't see how it matters?
Peace

Posted by: Porschef Aug 12 2013, 04:44 PM

The long term plan is to keep/drive it till I'm in the box...this is a winter project. I'm contemplating and assembling bits necessary to swap, if I decide not to do it it'll make a complete package for someone who will.

The bumpers I have are painted black, not chromed. I'm keeping it a narrow body, relatively stock, tho I ain't no CW....

Looks like the only thing I'm missing is a pair of fog light grilles. Just missed some in the classifieds..

It's a 914.... what's not to like???

Posted by: AZ914 Aug 12 2013, 05:24 PM

I ditched mine and never looked back.

The only way I would keep the BUBs is if the car was a near perfect stock example.

For Fog light grills, they are out there, heck I have some spare blacks, just need to clean them up.

Posted by: malcolm2 Aug 13 2013, 06:50 AM

So what about the details of the switch? I have a 75 and have rounded up some early, painted (black) bumpers. I have the dog-bones so now I need to mount. Anyone have any pointers on how to line and level?

I have also noticed that on a early car inside the front fender there is an additional bracket welded to the front corner where the bolts attach the front bumper. I guess that adds a little strength. Is that a place to re-inforce for the back-date install?

Clark

Posted by: ripper911 Aug 13 2013, 07:13 AM

As more and more of the later cars have they're stock bumpers removed it will make those that still have them even more rare and valuable.

Posted by: AZ914 Aug 13 2013, 09:22 AM

Malcolm,
On the late cars, there is a lip across the front hood line, and lips on each of the front * rear fenders that hold the rubber on. These need to be removed. The spot welds on the side pieces can be drilled and the piece removed.. the front lip needs to be cut.

Do a search on 'backdated bumpers' or similar... there are some threads out there that show this process, as well as the measurements for the holes.

Posted by: AZ914 Aug 13 2013, 09:24 AM

That is a true statement, however I wonder how long it will take for the 'late' cars to gain in value with the crappy exhaust setup, etc

Posted by: Krieger Aug 13 2013, 10:01 AM

No mater what you change on the car it will always be a 1975

Posted by: KELTY360 Aug 13 2013, 10:24 AM

I think that only applies to correct and original cars. Rarity and value do not directly correlate. Rarity, desirability and value do correlate. Opinions and perspectives may change over time but the fact is that most buyers, and collectors, prefer the earlier bumpers.

Posted by: rjames Aug 13 2013, 10:26 AM

I think the BBB look good on black cars only. I have an early set ready to go, but I haven't decided if I'm going to backdate mine or not. I was planning on doing it just for the weight savings, but this is the first time I've heard that the car feels different in a negative way at highway speeds with the earlier bumpers.

Posted by: Porschef Aug 13 2013, 10:40 AM

Hence my dilemma.. many good points...

btw, its a 76..

Another question: the tops have no puckering, but need to be brought up... is there a seriously good auto trim rejuvenation product out there that not only works but lasts more than 4 days?

Vaseline???

Posted by: cliffordbf Aug 13 2013, 05:54 PM

Take them off and take them as far away as you can. Then get early bumpers and put them on! Loving my backdate...only the back is done so far.

Posted by: Krieger Aug 13 2013, 06:04 PM

I use Vinylex Protectant for rubber, vinyl and plastic. I have been using it for 10 years on my bumpers, seals and dash. It has a UV screen in it. My car is not a daily driver and I park my car in the garage mostly, but seems to be doing its job for quite a while. It is not super shiny on the bumpers, but it does wake them up a little. I got it from Pep Boys.

Posted by: bigkensteele Aug 13 2013, 06:44 PM

I will be backdating mine soon. My car is in very good condition and with a little work, could probably fair well in survivor class at a local show. However, it was born a '75 1.8, and thus will most likely never be more valuable to someone else than it is to me. I have already backdated the exhaust, and when I have the time and a little coin, I will be putting either a 2056 or a six in it. 5 lugs and Fuchs are coming too.

Bottom line, I am never going to sell it unless something devastating happens, so I may as well make it what I want, rather than what some folks think that it should remain. Besides, I can always put the BUBs back on if I want a change.

Wow, welded square stock...nice work!

I haven't got those skills.

Posted by: rdauenhauer Aug 14 2013, 08:23 PM

If some one is interested Im gonna let this one go!

I should weigh it

Posted by: r_towle Aug 14 2013, 09:09 PM

You know how to use a hole saw?

Rich

Posted by: Rand Aug 14 2013, 09:23 PM

Sigh. It's a personal thing. I like everyone else, think they suck. What do YOU think?

Posted by: Rand Aug 14 2013, 09:28 PM

If you tried any kind of search at all, you would know how bad they suck.
But if you haven't been around or searched.... then let me just tell you straight up.

The BBB bumpers suck. Get rid of them and never look back.

Posted by: rdauenhauer Aug 14 2013, 10:08 PM

I guess he asked for opinions

Posted by: Porschef Aug 15 2013, 09:18 AM

Yes, I asked for opinions. Like bodily orifices, we've all got em.

And its all good.

Yes, Rich, I know how to use a hole saw. I'm a carpenter.

Welding, not so much.

Posted by: r_towle Aug 15 2013, 04:43 PM

if its weight you are concerned about....remove the rubber, mount it in a vice and have at it...you will see just how much you can remove.
Beware...you are making them less safe.

If its looks, well that is totally an opinion...beauty is in the eye of the beholder.
I like them on certain cars...and I like chrome on the others.

Also a cost issue...just finding and chroming a decent set of bumpers will set you back quite a bit....
A hole saw is simple, you can loose a lot of weight on those bumpers really fast.

I think you want the safety but the look of the old style, so take the time to search and read some threads about how to do it.
There is more work involved than just bolting on the new ones...

There is a lip you need to remove, then some paintwork (could be simple, could suck)

Just plan it out, get the dog bones, make sure the bolt holes are clean and not rusted out where the new bumper bolts in place....

Rich

Posted by: Rand Aug 15 2013, 04:46 PM

Just doin my dooty.

And you know it smells right.

Posted by: r_towle Aug 15 2013, 04:48 PM

you mean your opinion?

I think you have cornered the market on used bumpers so you are trying to start a trend.

Posted by: Vacca Rabite Aug 15 2013, 05:03 PM

Ditched the hydrolids as well and made some simple channels to attach them to the car.
My BUBS weigh the same as regular early bumpers, and I like the way the look.

Zach

Posted by: Krieger Aug 15 2013, 05:15 PM

Zach you have the total sleeper. Should have kept it secret. Now all these guys who thought they could take you in a corner with your BUBs, while your car is tipping over, will think twice...

Posted by: rick 918-S Aug 15 2013, 05:21 PM

I like the look of the BUB. If I had them I would weld up a simple frame to replace the re-bar or drill the shit out of the factory ones as Zach has done.

Posted by: r_towle Aug 15 2013, 05:26 PM

You can lose more...

Posted by: Porschef Aug 15 2013, 07:48 PM

Rand, I understand. And it smells right most of the time...


Zach, I remember you liked em big.


And, surgery CAN be performed by the common man!

Jeez, I'm getting nowhere here...

Posted by: bembry Aug 16 2013, 07:18 PM

I've seen some yellow and red cars that look pretty sweet with the BBBs on.
