Well here she is, this thing was really nasty on the outside. I guess it is 40 years old though. After about 45 minutes in the parts washer, I sprayed it down with some brake cleaner then blew it dry to get ready to put on the marking compound. The patern looked really good and consistant all the way around the gear. Also the back lash was good at .010 with no runout on the ring gear. It made me feel good seeing USA and FORD stamped on the pinion. It really is a shame because I dont think I have ever seen a ring and pinion with USA stamped on it. To think that stuff made in the USA just keeps going away...
All I have to do is match this pattern and I should be good.
I loaded the gear as hard as I could in this picture and you can see a circular pattern in this picture if you look hard enough.
Clean and ready to go in the car.
