it can be done,
both props off
disconnect handbrake cable from lever
disconnect difflock lever
support transmission
it may pay to remove exhaust centre section
remove crossmember
remove all the bolt joining the transfer box to gearbox (its bolted in both directions. ie some will have to be removed from the front (the really inaccessible ones)
remove transfer box, very heavy!
to refit read upwards :)
been a long time since i did it, and a 4post lift and air tools make the job much much easier, but it can be done on the floor
