So how many teeth are on the ring and how many are on the pinion?

Also, i'm thinking? (hoping) that the number may be stamped somewhere on the ring?

Its 41 and 13.............There is GM stamped on the ring gear and an 8 and 1 but that is it nothing else, im just stumped on this one

A 41 ring gear & 13 pinion = a 3.15
