Drop props, unclip wiring harness off gearboxes, remove transfer box, remove gearstick gaiter and gearlevers, undo clutch slave cylinder from bellhousing, remove starter motor, remove gearbox crossmember and support gearbox but allow to drop (watch fan blades don't ding radiator), remove lower clutch inspection plate, undo bellhousing bolts and the top 2 use about 4 extension bars running across the top of the box, pull gearbox off and change clutch stuff, put it all back together.
Removing front anti roll bar will give you more room, not essential but it does make life easier.
Have brew, fag, kick the cat and say next time I'll take it to the garage.
