If it was me...pull out the engine and box together. It will take a little longer but it is in my opinion easier than struggling under the car trying to wiggle 60kg of box out and then back in.
if however you want to take the pain.
drain gearbox oil
car on stands
remove front wheels
dont have too...but I find it easier to remove battery and tray
undo outer cvs
drop the front part of the exhaust from dump to cat to allow room for next step
remove transfer case and slide off tailshaft
undo hubs and release cvs by swearing and drinking beer while pushing hub to side. sometimes it is easier to drop the steering off the hub
remove drivers side cv shaft from box....more beer will help to ease pain of wacking fingers while shoving a wedge in to prise out the shaft
undo bolts that hold the drivers side jack shaft to the block and slide shaft from box
remove intake piping
remove airbox
detach selector cables
support engine with a something like this https://www.malz.com...oducts/DPTW4201 i use that and it works ok
undo the north south cross member amd the mounts from roll stopers
remove the two bolts that hold the slave cylinder and then the two that secure the metal slave line to the gearbox and move the lot out the way....this saves bleeding it later
revoe starter
undo all the bolts that secure box to engine....the box is now loose and will come out ...eventually...when you get the right angle sorted
goodluck...it isnt a job i like
