I found this list of parts needed using the search function. This list was taken from someone in NECO who did the swap. In addition to this, you will need an ECU from an MTX 'tour. If you want to "upgrade" the tranny, you can always send it to Terry Haines who can install a new differential (Quaife LSD would be my personal choice) and change out the synchros, spider gears, etc. I'm not sure what the cost would be, I've been told around $1300 for the treatment, but that was not from Terry himself.
