86 Cutlass posi question

[Koleslaw]

I want to a put a posi into a cutlass,
the posi is out of a s10 so the cutlass axels splines are not big enough.
So im look for ether a place where I can get some axels or posi axel gears

The best quality Axel actually came out in 1984, there were a couple revisions released in 87 (arguably equal or better) and 94 (not really recommended for obvious reasons). I'd start your search there.

I would find out first if the Posi carrier will even work with the cutlass diff. There was a few different options.

It fits I already have it in and everything
I was about to put the axels in and they didnt fit
I guess they are 26 splines and my axel gears are 28
so I ether need to find 26 spline posi axle gears or 28 spline axle
That are the proper length
I already to the pnp and ripped apart all there ten bolt diffs and I cant
find the exact axles I need.

Thanks, real helpful. Lololol
So I need 28.5 in, 28 Spline axles
Does anybody know a place in Calgary that does axles?

THIS is an Axel, as referenced in my initial post.

There are two types of G-body GM rear ends-7½" and 7 5/8". I think you have the 7 5/8".
The 26 spline are from the smaller rear end-you need axles from an 87+ era G-body or an S-10/Astro Safari van.
You can check 8.5" rear ends as well but I can't confirm they will fit your application.
