Loosening the bolts was one of the first things I did, I think while the wheels were still on, but I might be wrong. If the handbrake is still there then put it on, otherwise stick the engine in first gear. I don't recall it being too difficult at all.

The bolts have a loctite coating which breaks down under heating. If needed, apply heat to the bolt heads. I had enormous difficulty in separating the drive shafts from the diff until I applied heat. Be careful though to keep the heat away from the oil seal.
