The engine tabs on the frame will need to be cut off and replaced with new ones. The tabs on the frames are different as well as the mounts. If you get an engine that's from the same year it's easier then trying to match up changed stuff like connectors and fittings.
You will need to replace the transmission and the input shaft on the transfer case. You'll probably want to replace the radiator to a 3 core as well. You will also need to get the pedal's from the manual, cut a hole in the floor, get the shifter boot and the shifter cover plate. Grab the tach/speedo as well. Then you'll need the engine harness and PCM.
