90 Shell Swap!!!

[Slippi84]

Ok I have been dodging this for long enough my shell is shot. It's got rust on rust and now brake lines are cracking and what not so I have to abandon ship and chang everything over. This local has a 91 shell that has trans rear and all that good stuff but my car is a 90 which is the bastard child of the dsm's where a whole bunch of stuff is 90 specific even from the other 1g's. I just need to know everything that will or won't bolt up and what i'm dealing with this is what I have come up with so far.

90 transfercase
90 coil pack/transistor pack
90 eprom ecu(will the the 91 harness plug up to a 90 eprom ecu and work?)

Throttle body, but you can wire the TPS to work. Its just a difference in the harness and the way it plugs in. I put a 91 tb on my 90 just to elimintae the FIAV valve and IAC, its not to hard, wire colors match up the same, then you just have to have the additional wire for the TCS extended and hooked up. And with the ECU, i think its 2 pins that need switched. heres a link for a 91 in a 90...same situation though. http://www.dsmchips.com/1990ecu.html
