Rear Diff

Most folks run a dana 60 for 10's and faster. Me personally, I have a Moser MO875 fabricated housing with a backbrace...3200-3250 lbs (not really sure), foot-brake car, mid 10's in the 1/4. If I ever break this one, I'll probably move to a dana. Heavy cars, and trans brakes kill 8 3/4 rears...if you are light weight and foot-brake it will probably last for years.
