Checking Gear Ratios

[boy&hisdogs]

Do the factory GM gears have the ratio stamped on them anywhere? I've looked at a few of them and didn't see anything on the ring gear. Is there a way (other than counting turns) to check it in the field without the RPO? I'm looking to buy a 14b SF with 4.10s. Let's assume It's just the axle assy and the donor truck is nowhere to be found.

Yeah they do but it wont come right out and say 4.10 on it.

Like mine have 12:41 on them which is 3.42s

On the ring gear right? Dunno how I missed that. What about the front?

Yup on the ring gear. Same for front
