Dana 70 rear differential overhaul

Has anyone ever had the pleasure of rebuilding the spicer 70 rear differential? I've purchased new carrier bearings, a shim kit and a limited slip clutch pack, and I'm ready to tear into it today. At 245,000 miles, I figure the bearings and clutch pack are about due for replacement. I've got a hydraulic press to press on the new bearings, and a dial indicator to check the gear back lash, however, my Chilton manual does not go into too much detail on setting one of these up.
Does anyone know what the ring to pinion gear backlash tolerance is? Also I don't know what the maximum allowable end play is for the carrier bearings.
