i do it, and frank does too, (i copied it off him)
what i do is, i go under the car and remove the rear engine mount, all the rest can be done with the wheels on the ground
support under the engine and 'box, i use chacks of wood, part take the repmaining 3 mounts off, seperate the engine and 'box (about 5 bolts) pull the gearbox off the engine, might need prying off and a bit of a riddle, theres enought adjustment in the shafts and linkage to shuffle it out of the way, then the block will come out indapendant of the 'box.
i think theres pics in franks blog.
ive also adopted this method of changing a flywheel and clutch, leaving the engine and 'box in the car.
hope this helps.
