well you have to figure, basic upgrades for some cars deal with other peoples stuff. DSM guys love using our out of date MAFT's. Supra guys take our TH400's, powerglides, TH350's, and 12 bolts.

aslong as the chassis and powertrain are the same then sure, i dont care...but the rear end? what performance value does that provide? longevity, yes, but any rear can get a spool practically, any rear can be welded for a live axle, and gears a plentiful for all of them. but even the manufacturers do that crap, T56's...chrysler, ford, and gm all use em...the Dana rear ends, i know GM and Chrysler use em..
