Won't most rear end or transmission shops have shim kits or whatever u will need to swap over to posi? Anyways, thats what I did Duke over at Phil's Transmission in Mt. Morris. Bought the posi and they had the shim kits already available. If that is what ur talking about.

Pablo, could you tell me which one I would need for my stock rear end (3.08). I want a performance locker.

That powertrax sounds nice, but how long can it last on the street?
I believe the guys rear end is a 3.08, it's a 92 RS with a 305 and an auto. It's an ugly purple color too hehe.

I'm going to check out SLP's. When I did mine I installed 3.73's with a posi, but it already was a posi rear end so I didn't have to get spacers and everything (had someone else install it though).

Thanks guys!
