basically the complete swap engine trans ecu, linkage. If you pm 92'CXhatch(Keith) he can tell you for sure he knows all of that shit!! your going to need a mount kit prefable from hasport. Make sure the ls ur getting is a cable trans on it cuz I belive the rexes are cable not hydro. You need either axles made or even 90-93 teg axles is what I think ppl have used in the past.
