Okay, I think I have nailed the pattern on my 9" Motive performance ring and pinion setup. I killed the older thread so there would be no more confusion, plus I had the many photos mixed up. Thanks again to all who have helped.
The following setup use a .019" total shim pack and has .008" backlash.
Please check these patterns out, am I ready to go?

Can you get another pick of the thrust side? It looks a little deep but kind of hard to tell

I guess I am confused, what is the thrust side?
Any other suggestions for a better picture.

Another shot of the .020" coast side.

Here are some other pics for reference showing .020, .021, .022, shim packs.
Gears are Motive Performance for the 9".

Looks like adding shim is moving the drive pattern to the heel as well as moving the two patterns apart. Once again guys all the pics in my old deleted thread are bogus, they are totally worthless.
I checked the backlash at .008" and .0012", the change was nearly non-existant. Are the two patterns supposed to be more centrally placed rather than spread apart?
Now what?

Update:
Went with the .020" shim pack and a .009" backlash and it is very quiet. What noise I am getting is being amplified by the tunnel mount torque arm. The final pattern certainly was not 100% ideal, but it was certainly the best I could get.
Thanks to all that helped.

The way some gear sets are cut for strength so they make a little noise anyway. I have a Pro Gear set...its noisy as hell, and I have rod ended TQ arm and heim joints on everything
