You'll need to either make, modify or buy swap parts. Mounts, oil pan, oil filter relo, headers, etc. Using a full size t-case may cause clearance issues to the frame and fuel tank. The larger engine (front-to-rear) and increased cooling requirements may force a radiator change.
hey thanks alot i just figured it would be a good palce to start by buying a whole truck so you would know the parts would bolt together and wouldnt need to get addapter plates and other stuff custom make for the motor trany and tcase to all work together.
