Carefully count the teeth on both gears and divide the pinion number into the ring number (of teeth) and you will get a number like 3.55. That number you get will be the gear ratio.

Another idea is to look at the front differential for a tag. The front would be the same ratio. Except I had a 1967 Ford Bronco that had 4.10 diff in the front and 4.11 ratio in the back. Figure that one out. I'm guessing the front would pull (lead) slightly.
