In my former ride, 79 CJ7:
I swapped in a Dana 44 from a 86 CJ and ran 35's with that. Used a Dana widetrack in the front, TH400 out of a CJ and a Novak adapter to a Dana 300 transfer case. Never had any trouble out of this setup, as most of it was an easy swap. I used a Lokar shifter for the auto tranny because it was about the same length as the stock shifter and it bolted right up.
