My 3rd set of eyes counted "40" on the ring gear, if that is of any help???

Any chance you want to take a stab at any of the tricks or tips in this "Tech Tip" Reading Indented Numbers to try and better ID what you have. headscratch

You can still see some of the stamped numbers on far left and right as the grinding wasn't complete, and one of these tips might bring more into view to help???

Just a suggestion. wink
