I have an interrested buyer of my ($275) NP435. But first he's needing some info on what he's getting into. His '82 Bronco has a 351w, c6 auto and (?)transfercas. Do U guys think he'll need to mess with drive shaft and make alot of modifications.

 

Just posted it on your other question, but it'd probably be better here:

1981 Ford Bronco NP435 Swap

If I remember right, the drive shafts are the same length, but someone else may know better.

It's definitely involved, but doable. Just a lengthy project.
