I got my new pumpkin today. The only issue is I don't understand what is stamped on the ring gear.

It ia a 72 3/4 ton center carrier. The guy guaranteed it was a 4:10. I don't understand the numbers on the ring gear it says "GM 10:41"
(then there is a bolt)
"12 (space) 1970"

What gear ratio does this equate to???

Thanks

If it can be built ... It can be fixed.
