Got back into it this afternoon and removed the entire exhaust system, battery, radiator and disconnected most of the engine wiring and the air intake.

It was hard going at first with lots of rusted nuts in hard to reach places. I then decided to take out all of the easy stuff first and the extra room it gave me let me easily undo the difficult nuts and bolts. The auto gearbox has an oil cooler built into the bottom section of the radiator, so I will have to get an aftermarket oil cooler to fit in it's place.
