Hi All, I have a 1988 2 wheel drive GMC dually and a 2 wheel drive 95 Dodge 3500 with 12 valve Cummins engine, both are regular cabs and auto transmissions. I am thinking of swapping the Cummins engine and trans into the GMC and was wondering If anyone has done this personely, and what issues I might encounter other then engine/trans mount fabrication.
