Nothing overly complex TBH and other than the obvious removal procedures of propshafts, starter motor, shift linkage, speedo drive, electrical connectors etc I'd note the following:
1. Remove the transfer box from the main box first. The FSM procedure shows removal as one unit but it is HEAVY! and splitting the two units first makes it lighter and easier to handle. I changed mine about 3 years ago by removing the main + transfer boxes as one, really struggled and made a right spice shop of it, ending up damaging the clutch cover plate and having to do it all a second time!
2. There isn't much room between the bellhousing and transmission tunnel which makes access to the housing bolts difficult, you'll need some long extension/wobble bars. Removing the Xfer box first also gives a bit more room to manoeuvre the unit, especially on replacement. Once the box is out, changing the clutch itself is pretty straight forward.
Edit.....Chris beat me to it!
