Posi swap

Which rear diff. posi unit will swap into a '92? I've seen units for S-10 and camaro models but are they the right spline or size?

Re: Posi swap

No, too small. They are 7.5 and 7 5/8", urs is a 8.5, 28 or 30 spline depending on year.

Re: Posi swap

Maybe a posi unit will help out on wet roads and have a little fun in it...
what spline count would a '92 be?
