There is probably thread already out there that answers this question but I changed my rear end Lube last weekend and i wanted to see whats behind the pumpkin cover. here is a pic of the markings on the ring gear. Can anyone tell me what I've got?

Markings are 3682104 GM 7-32 10 1967

Thank you!

Hi Ferno,

The 7-32 tells you the gear ratio, you have 4.57's. (32/7)
