98 Dakota 5.2 drivetrain in 66 Dart?

We put a '96 5.2 into an '84 Ramcharger. Mechanically all we had to do was fab up a trans crossmember and shorten the drive shaft (as I recall). For the electronics we removed all of the Ramcharger wiring and used the Dakota wiring. A few circuits needed to be modified, but that was it. I know there is a company that makes (at least for later A-bodies) fuel tanks for this purpose (my son just got one for his wife's '65 Mustang that's getting a modded '89 5.0/5sp).
