They usually work harder to get things right on the high production gears than they do with the low production stuff.

Thats nice to know. Thats the reason I got rid of the 7.5 10 bolt. I couldnt get the gears to setup in them for anything and not make noise. Plus they are weak. I thought with the simpleness of setting up the 9 I could get this thing done and in the car. Looks like I might be buying another ring and pinion. Do you just mainly use Yukon? Should I try to find an original Ford ring and pinion.
