Backlash on both pictures was 0.008 - 0.011 checked 4 places. Gear set paper work said set 0.008 to 0.010. I think a couple more for circle track racing.

On the first shim pack, I checked about a dozen or more places and the backlash varies a little under 0.0035. It is difficult to get exactly 0.008 at the tightest spot and have the hole in the cup lined up. From what Rick said, it sounds like I could let it slip under 0.008 without any problems.

Manual I have said to tighten right cup 2.5 to 3 holes after contact and cup should always be turned tighter on its last movement. Both pictures the pre-load was set 3 holes.
