Okay, a couple back steps....

This is a replaced axle. It came from Jasper in Atlanta in 1998 and was put together and installed in Newark, NJ (Scary place for a southern white dude to break down....) I'm pretty sure that they used the origional gear ratio as they didn't touch the front and they are a paired set of gears....

So, it would have 3.47:1 gears (theoretically) and are most likely 3.55:1?

Question still remains regarding the 11480 and the 5.....
