9" gear pattern check.
No, I don't know of anyone that has one. I'm in Surgoinsville, TN. About 1.5hrs east of Knoxville.
It was a slow night at work last night I did a lot of searching and reading. Apparently this is pretty common when you put deeper gears in a 9". Since the pinion is smaller in diameter and the ring gear is thicker it causes clearance issues.
I think I'm actually going to pull the carrier back out and grind the toe of the ring gear down a little bit and just be careful to go slow and not get it too hot. There's actually a note about this problem in the tech section on Randy's Ring & Pinion's website and grinding the ring gear is their suggested fix. Since it's on the toe and away from the contact pattern I think it will be fine. The casting is kinda thin there at the pilot bearing housing and they say if you grind on it too much it can crack.
I appreciate all the help and input though. I'm on graveyard through Friday morning so it may be a day or two before I get to tear it apart. But I will post back with what I come up with.

Re: 9" gear pattern check.
I didn't really take many pics but I tore the 3rd back apart today and ground the ring gear toe down just a bit. I went ahead and did the ring gear for the other 3rd as well.
I got the first one put back together. The ring gear clears good now, and the backlash and pattern both look good. I also got the other 3rd set up today but I didn't take any pics of it. It looks identical to the first one though.

Yeah, apparently it's a pretty common thing. I clearanced the case first but it still rubbed. A few minutes with a flap wheel on the ring gear and it clears good now.
