Ok I'm stumped. Rear end help please!

That's learning 101, no biggie, just time lost for you. Thanks for coming clean, cuz we could have been racking our brains for ideas, soon.
May the Force be with you.

LOL it just wasn't adding upÂ…but I've got to wait to do any more work on it because I realized one of the pinion teeth has a small chip at the end of the tooth. These are used gears and I don't want to take any chances, I'll have new gears tomorrow.
