Does anyone have any information on the different length u-bolts for the rear u-joint. I am having difficulty finding a u=bolt that is long enough to go through the yoke. I received a pair from Yearone that have the correct width but they are .25 to .50 short. Any help would be appreciated!

The car is a 69 442 convertible 4 speed manual tranny

Thanks
Mike

 

This is a surprise? Nobody else ever have this issue or see the difference? I'm pretty new to this so am I missing something? Feel free to call me an idiot, I will not be offended. I'm just looking for a resolution to get a part

 

Are you sure u-joint is seated in yoke?

 

Yes the Joint was seated correctly

 

Yes the u-joint is seated correctly.

 

I ran into this problem too. I couldn't find long enough bolts at any of the auto parts stores in town. I installed a 69 diff. in my 71 using the 71 driveshaft. This has been five or six years ago but I did get the right bolts from 507olds. It had something to do with the yoke and maybe u joint combo? I know our cars are not exactly the same but, hopefully these photos will help.

 

Mine would be the u-bolt type so hopefully 507Olds can come up with another set. Thanks for your inpot!

 

I had the same problem I went to a shop that just does rearends and gave them a short one said I needed longer gave me a used longer set for $5 worked perfect

 

I tried the same thing and the shop I went to wasn't as helpful. The only information they offered was the u-bolts are all standard lengths and they wouldn't have anything.

 

I will get a pair for you. I have used ones. I also kept a HELP package from when I bought a new set,as I had to do some research when I was at the parts store. I have the HELP number.Might be Dorman.

 

Used are fine with me. Thank you Brian

I'm not sure what you mean by a HELP package?

 

"HELP" is a registered trademark brand of hard to find parts, usually carried by larger auto parts stores; you might try a local store, or try here:

If 507OLDS has the Dorman number, you should be able to order some from your local parts store!

 

That would work for me. The diameter I need is 1-1/8

Brian, Either way works for me- if you have a used set or the Dorman PN

 

I have been keeping USED ones also. ALL the NEW aftermarket parts are ALL over the place with length. It is truly incredible the crap that is out there. The way of the future for all products. No one gives a hoot what is out there UNTIL they need the right part of course and it personally affect them. Jim

I have gone to parts stores and had them pull all the u-bolts off the shelf that fit the application and did side by side tests and they could not believe they were all slightly different from u-bolt to u-bolt and manufacture. SO I can only tell you pull as many as you can at one store and take the best ones you can find. Jim

 

There are 3 Dorman U-bolt kits-
8002
Application Summary: Buick 1980-75, Chevrolet 1986-53, GMC 1986-73, Oldsmobile 1980-75, Pontiac 1980-75, Pontiac 1970

8004
Application Summary: Ford 2006-65, Mercury 1980-65

8008
Application Summary: Jeep 1980-62

 

None of those numbers.The correct number is 81002. I believe I had to order these last time,but they match the originals perfectly.

 

Oh man- all the numbers should be 8100* not just 800*

 

Went to the local Fisher parts store and they were able to get the Dorman 81002 u-bolts. Brought them back and whala! perfect fit! Thank you all for your input!
