Do you have access to the VIN or the RPO sticker of the donor vehicle?

If not, if you have the complete rear axle assembly still together, you can always put a mark on the end of the axle and count how many turns of the input shaft it takes to turn the axle 1 revolution.

there's usually a tag off one of the diff cover bolts. they are thin and flimsy so its not uncommon for them to come off. id think you would want to change the fluid in the rear diff and inspect it and not just assume its fine. if your going to sometimes the ring gear is stamped. kinda tired but theres something about counting teeth too.

Here’s the stamp on the ring gear that he mentioned.
