thanks a lot jim. Do you know if GM still requires the limited slip additive be put in too? I know a few older posi equipt cars I had, and even my 93 chevy P/U seemed to perform better with it. Also Is the gear size 8.5 or 8.6? I've heard both and not sure which to believe. And to to top everything off, I did get an appointment with a performance outfit not too far from me, that's ready able and willing to do the install, and give me a hell of a warranty on their work. So now its just a matter of getting the parts ordered, and my quick little

becomes my crazy fast little rocket ship.
