94 Dakota 360 5 speed into Dart?

Hey, someone is offering me a 94 dakota with a beefed up 360 (don't know what it has in engine yet) has f & b throttle body and mopar performance computer and headers (will these headers fit in a 68 dart? It has a 5 speed (not sure which one) after market wheels. All for 2k or less.

Would I be able to get the drive train into the dart? If I were to make it 5 speed, would I need to buy the pedals for an A body and what else?

Not sure what rear end it has I'll ask later.

Would this be a good idea? Or to much of a hassle?
