Does anyone know what the pinion gear nut should be torqued to? I don't have that information and need it right away!

The actual torque on the nut isnt what is important, what is important is the pinion bearing preload torque. You tighten the nut a little at a time and measure the torque needed to rotate the pinion only -- the diff should not be in the housing when doing this. If I remember correctly, preload torque should be around 15 inch pounds for new pinion bearings, and about 10 inlbs for used bearings. The torque on the nut needed to get the correct bearing preload torque is usually around 180 to 200+ ftlb, so use a long breaker bar, and be prepared to do some serious grunting to tighten that thing.
