Having a hard time finding a reasonable deal on a posi rear for my 71 cutlass.
Found a 66 reasonably priced,but owner states the 66 is 1 inch shorter.
Does everything else line up correctly?
Any other easy options for a posi?
Thanks.

 

Can you not build the corporate 10 bolt that's in it?

 

Long story.
I bought a project with a incorrect rear end,and pulled the open rear from my cutlass for that project.
I now want to upgrade to a posi,but have no carrier.
Thanks.

 

I would put out a wanted ad, if you can get a '71-'72 10 bolt for cheap you can put an auburn posi and gears in it for less than $1000. Mine is holding up just fine, and it was built in 1998.

I know Brian Trick (507olds) builds rears as well...although that may be over your budget.

 

There is an abundance of posi units & gears for the 71-up 8.5" 10-bolt.Your 71 Cutlass came with one of those rears originally,and that sounds like what you are trying to build.

 

8.5 would be great..The problem I'm having is finding one at a decent price.
I've recently lost my job,and the car is on stands in the garage.
My drop top is sitting in the elements,and having a car without wheels is really bumming me out...

 

I have a posi unit from an 89 wagon with the tow package here that I could pull apart and get you a fair price on. It would be an auburn cone type and not the trac lock style though. I don't remember if it was a 3.08 or a 2.73. I'd have to pull it apart and check. Let us know what the budget is, and we can help within reason. I also have a good set of 3.08 gears here.

 

J- That posi unit is 30-spline,and he needs a 28-spline.
