      Ring gear pattern help

      I'm building my first rear end, it's a 8.5" 10 bolt out of a 70s nova, I've set it up with a Detroit TrueTrac and a new Yukon 3.73 ring and pinion. Backlash is set to .007-.008 measured across multiple spots on the ring gear. This seems to be the best pattern that I can get. Can anyone's more calibrated eyeballs make a suggestion if this is acceptable or if they think I need to adjust the pinion shim? Thanks guys.

      I think it looks pretty good. I would roll with it.
