Anyone have any idea, or can someone tell me where to look for it? Thanks!

probably a 4.10, but should be a metal tag between two of (either frt or rr axle) cover bolts that has the PN & ratio stamped on it...
If it's missing that plate, lift the axle and with the t/case in neutral, spin a wheel and count propshaft rev's...;)

More likely it's 3.31:1 or 3.54:1. 4.10s were optional if they were available at all - the '80 FSM would tell you what ratios were available in what models.
You can also take the cover off and look at the tooth count stamped into the outside edge of the ring gear. For example, "39 11" is 39/11 = 3.54.

Oh, this truck has an AMC Corporate rear axle, so you need more info.

The front axle is a Dana 44, and should have a tag.
