9x37 ring and pinion. 4.11 it's cleanly stamped right on the pinion shaft along with a little teq or something that looks like that. only other numbers on it was 82 and 77. i counted the teeth 9x37. the Toyota 4.10 R&P is a10x41 i believe. I'm no expert on 3rd's. i pulled this one apart to get the Toyota solid spacer out. i plan to use it in a newer 3rd i'm going to attempt to rebuild and regear.
