You'll need something to activate the electronic controls for overdrive
and the lockup torque converter. I think either Jet or B&M makes a kit
that runs on engine vacuum. You'll probably need different engine
mounts. Schumacher Creative Services (http://engine-swaps.com/) will be
able to help you more with the engine swapping. As for the
trans/transfer-case mating up properly, I would think that the later V8
Dak's ('92-96, or until the swap to the electronic transmissions,
anyway,) would have the exact setup you're looking for. This would be
where someone with a 4x4 should step in and give the rest of the info. ;-)
Sounds like a nice project, by the way.
