Looking at the pic of the ring gear numbers I see 47-12 not 4/-12

So you take 47 divided by 12= 3.91666, in other words you have the 3.92 ratio. That's a real good ratio for a 4wd half ton

3.92 was the standard ratio for the 4x4s in 1962. That's what my Suburban came from the factory with. It's got 3.54s in it now.
