Default 14BSF Gear Pattern Check

I am rebuilding a 14 Bolt SF axle. I ran a pattern and would like another set of eyes to take a look. It seems to me that I should add shims to the pinion due to the drive side pattern on the gear. Second questoins is how much should be added at a time 0.005"? Here are some pics of the pattern.

Received an answer on another forum and though I would update this for completeness:

These are Yukon 4.88 on a Trutrac with a 0.030" pinion shim and backlash at 0.007"(spec is 0.005-0.008"). I got them from axisT6 last year and just now getting around to gearing.

And just to make sure the info is complete, here is his response in the gear install how to thread:

I'll add that and run another pattern and report back. Thanks axisT6!
