Re: I NEED a posi
You can easily just swap out the center diff unit with a posi unit(make sure your using corresponding axles ie:26 or 28 spline)
Or you can swap in a whole different rear end 3rd gens would be easiest but you can upgrade to a 4th gen rear too.
If you end up needing just a posi unit to change out the diff I got one from a 98 camaro with 273s.
