Is there anyone who can give me some advice on how to replace the engine in my KingCAB Diesel 4x4? I've bought a complete car that we've stripped of all parts needed. The frame on that one had rusted so badly it was in two pieces...

When we removed the engine we noticed that there isn't enough clearance between the front axle and the oil pan, so that lifting out the engine was rather difficult. In the car we scrapped that wasn't much of a problem since we could take out the complete engine+gearbox in one piece. We had already removed the body from the frame so everything was easily accessible. This isn't the case with the car I'm replacing the engine in though. What is the easiest way to do it? If I remove the prop shaft, can I move the gearbox enough to get enough clearance or will I have to lift the body off the frame?
cheers,
Anders
