I am pretty sure the bellhousing bolts on those and most others are metric 12 x 1.75, I had to run a tap through some recently and that was what I used
Just a matter of personal preference but I do all the bellhousing bolts from the bottom with long extensions, and the t-case and trans crossmember removed. Easy access if you let the trans pull the engine down. Tried them from the top many times but I always end up gouging a chunk out of my arm when I do that.
Also personal preference but I don't feel that the slave cylinder disconnect tool is worth a crap. I've bent several of them and they don't push the sleeve in far enough anyway. Small flat screwdriver - work your way around and tap it in.
