Re: torque for the rear ujoint bolts
You mean in the driveshaft itself?
The 8mm/10mm ish ones? Those get 20-30ft/lbs MOST or they shear and suck to weld a screwdriver to to twist them out.
If you mean where the pinion/driveshaft meet (some have bolts, some have u-joint straps) then those get a little more but not much, still under 40ft/lbs.
If you mean the u-joint straps that mean the driveshaft, I find it amazingly easy to just drill through the holes in the pinion so you can use u-bolts to hold your u-joint/driveshaft to the rear pinion, makes it a friggin breeze to change and if you ever strip the bolt you can just grinder/sawzall it right out.
