  • Rear Ends?

    Would any of you guys happen to know a place I could pick up a 3.73 Posi rear end? I've already learned that the 4th gen rear ends are wider then ours so that is eliminated. Also if I didn't get a whole rear end, could perhaps change to a posi w/ 3.73's? I'm trying to learn about this whole thing. And it seems to me like my next mod should be a different rear. Becuase right now it's a 3.08 open diff. Any thoughts and help is greatly appreciated!!

                  3.73's would seem a little drastic with the auto since our trannys won't shift into fourth when floored. I thought about changing the gears in mine but I think I'd end up running out of third gear with that small of gear in the 1/4 mile.

                    So would 3.23's or 3.42's be more logical? Thanks for all your input.
