I want confirmation before going forward.

Great advice!

Good luck with it. Let us know how it turns out.

I like to think of myself as a "bottom-end" expert

The initial reading taken was off by .0005" Pinion run-out measured with proper device is .0125"

Measured another 2010 crank from a factory 103 with a reported 1500 miles. Run-out at bearing race was .006 on each side. Pinion end was far worse.

Any confidence I had in a factory crank is diminishing. IF anyone has a good one, I am happy for them.

The S&S route with left side Timken upgrade appears to be the best solution.
