If I remember right, you will need to make/buy a case spreader.
Micrometer for measuring the shims, dial idicator w/magnetic base for the backlash, may need a puller for the yoke. Maybe a torque wrench and pry bars. Grease marker or some similar to check the pinion/ring gear depth.
Plus the obvious tools for removing the bolts.
May be others, but that's what comes to mind. Been quite a few years since I've done one.
