@ Mark, it's very easy, remove the seats, steeringwheel, carpets and the gearbox & propshaft cover.
Put a thick piece of wood under the magnesium belhousing.
Remove the 4 propshaftbolts, handbrakecable and 6 gearboxbolts.
Put your jack under the gearbox, and work it loose.
My box was leaking at the front, it needed just a new oilseal.
If your box is leaking at the back, look at Gomog.com
Good luck.
