Gear pattern,GM 12 bolt car.

[chevelletiger]

Hi all,im setting up a US GEAR 3:73 street ring and pinion.
I used a T&D Machine pinion depth tool,and it read I needed to use a .036 shim,used that but the pattern didnt look right,and I had .011 backlash on the ring gear.
Today I used a .034 shim,and got .009 backlash.
How do my patterns look?,I used a .032 and the pattern 2as really high,I didn't take pictures thou.
Thank for any help
