How do I find what Gear set is in the rear?

How do I find what Gear set is in the rear? I have the tow package and was hoping to have the 3:73..probably have 3:21 as I originally thought.

Where do I look on the rear axel or diff. case?

One way to do it is to lift the rear wheels off the ground and spin one of the rear wheels and count how many revolutions your drive shaft makes. Ie f one complete revolution of the tire rotates your drive shaft 3.21 times then you have 3.21's if 3.73 times then you have 3.73's etc.
