^^x2^^ Although "tub" to me says it doesn't have the powertrain in it any longer, right? It'll be a "work in progress" for a long time because of the electronics. A 91 is probably a Renix.

1990 was last year for RENIX system. Regardless, you'll need to have the transmission control computer and wiring to make it work. Be easier if you were pulling everything from a complete donor vehicle, 1991 - 1995.
