Ring & Pinion Backlash of 0.012, but good pattern

Like the title says, I have a set of 3.70 AAM gears that are showing a good pattern in bottom (toe) 1/3 and 1/2 towards the root. However, the backlash is dialing in at 0.012; slightly outside the 0.006-0.010 recommended. Will I be OK? If I shim the ring toward the pinion, I'm afraid I'll move the pattern in toward the toe to much. Thoughts?

Damn mods are making me ask a lot of questions lately.

rather a bit tight than too lose IMHO...when I did my AAM 3.91's it came in at .002. With back lash that high the rear will be loud and lower life expectancy. Good luck!

Late model AAM gears uses a 2 cut setup which the backlash is in the 0.003-0.006 range while the aftermarket and older OEM gear sets(most models) is a 5 cut gear which 0.006-0.010 is ideal. The 2 cut gears does a weird pattern even when perfect.
