quick question

I jacked up my rear today and when I spin the tires, they spin in an opposite direction. Does this mean something? Also, is the stamp number for the axle ratio on the drivers side or passenger side rear axle housing?

Means the rear most likely is non-posi.

Ratio is stamped on the ring gear, usually.

The RPO code is stamped on the passenger side axel tube near the diffrential. There is only a 50/50 chance of there being enough left of it for you to read it though. best way to check is to pop the cover off and read it.
