depends if the top bolts are in or not really, im doing mine at the mo and the top bolts not being there makes it a lot eaiser. I had my box out within a couple of hours. I removed: Props, battery cables, starter motor, clutch cylinder (im changing it), centre console, gear & transfer box stick's, hand brake cable then all the gearbox bolts then dropped it all back onto the cross member. While its out im doing the clutch, arm, spigot bearing and rear main oil seal. it should hopefully be going back in monday
Any how I hope that gives you an idea of what's involved
