Details:

It comes with the pinion depth shim it ran so that ll ease setup. These shims are not reproduced and very hard to come by. The pinion is very clean. I think it'll be a good runner.

Some light pitting on some of the ring gear teeth but its a good set. Tough to find a set like this. Within reason. Its a 4.10 gear set.

Easy shipping compared to a full dropout. 41 10 teeth. What you see is what get. This is the ring and pinion from a 1971 c20 pickup.

These 4.10 sets are hard to come by. I am open to offers.
