Some of the GM posi-traction rear ends have a tag bolted on the right side (if someone didn't remove it)..... forward of the diff cover. It's about 3/4" wide and about 2 inches long with the info on it. 3:73's and 3:08's were pretty common, but there were others also. Check for a tag, it'll have info on it.

Also look on top the passenger side axle tube for a stamping. It will be letters and numbers. Then post it here and someone will look it up for you.
