Update. there are 41 teeth on the ring. This is what happens when an aggie trys to count!

So, would the 10:41 stamped on the ring gear give me the pinion/ring teeth count? 10 teeth on the pinion, 41 teeth on the ring gear....I guess I was looking at it as ring/pinion. They stamped it pinion/ring. Sometimes it helps to just stand back and draw it out.

So I just got lucky in the scrapyard and got my highway rear! Sweet. while i like driving 40 in my old truck, 55 may be better, and the motor will appreciate it as well!
