There should be a tag held on by 2 of the diff cover bolts. It should also be stamped on the outside edge of the ring gear, or you can count the number of teeth on the ring gear and pinion and divide them to get the ratio.

If it's a 2.5 I think it has to be a 4.11 ratio if stock, and if it's a six I believe the most common was 3.55's? I'm still learning too, but thought I'd chime in with what I "think" I know.
