I'm not sure what you mean by "which gears are which". You have a 12 bolt axle, with an open carrier. That means you do not have any kind of locker, or posi-trac.

I see that you have a GM carrier, and it appears that the ring gear is GM as well. I can't see the numbers on the rng gear well enough to determine what ratio you have.

What transmission will you be running? What rear tire height/width? This info will help give a better asnwer.
