Hello,
I'm looking to swap out the rear on my 1965 Skylark. Presently have original non posi 278 rear gear.

Checking to see if anyone here has a complete posi rear in good shape that they don't use. Otherwise I will have my original rebuilt.
The 1965 BOP rear that I require has unique flat spring perches and is a little narrower than other years. I'm located in N.Y.
Thanks

 

I have a completely rebuilt one with 3.55 gears but shipping from the west coast of canada would be a killer

 

Thanks,
Your right shipping cost would be a problem.
Best for me would be local pickup or reasonable drive with pick up truck.

 

I had a W-27 3.91 posi from a 1970 442 in my 64 Cutlass for 15 years. They do fit I just don't remember how the spring fit but worked.

I also installed a '70 3.91 type "O" posi rear in my '65 Cutlass. The lower spring perch is different than the earlier one, but works fine. The only difference is that the later rear is 1" wider than original. A little creative re-contouring of the inner wheel well and I could run 275-60R15 Drag radials without any issues.

 

Gerald,
Thanks for the info regarding other options for my 1965.

 

your pretty close to me though, do you need any more 65 parts? i got a bunch of smalls from HonestDaves hoard

 

Stan ... I was offering to sell him one, i'm not looking for any parts right now, complete opposite i'm selling off my complete project

 

sorry just saw your other post with the bumpers etc, how much do you want for the rear end? im always looking at 65 stuff
