8 3/4 diff yoke

A little file work on the teeth ends if you want. I’d hit the outside diameter (that the seal rides on) with some Emory cloth at the least. What do the u-joint saddles look like is more important. Run a thread cleaner/restorer in the u-joint strap bolt holes and flush out. That’s what I’d do.
Nothing wrong with what you have there. In my opinion
