[Pontiac1976]

Any of these #'s on the diff does it still have a tag or stamping on the housing.
82 should be 10 bolt, has heavy load in rear. I'm guessing 350 Diesel was being set up for pulling. Did it have a bigger diff and that why it was not marked. If you can't find any # that will help then pop open the cover count teeth.
