What was the original Shim on the factory set up?

I feel like you need to go deeper to center it up and possibly tighten the back lash a little.

the original shim was .025 which is what this pattern was made with.
The coast side seems deep to me
and the drive side seems good
the backlash is set a .009

Pattern falls into pinion too deep category
im going to decrease the pinion shim to .020
and tighten backlash a little

These are a little tight back off to .020 or even .015 to get your coast from being too deep.

pinion shim .020
backlash .008
I think this pattern looks like a good competition pattern
im probably going to run it unless one of you guys see something i dont
Looks good to me
let me know if i should run it with this pattern

give it a try try and see how it goes, I am a feel type person where I can tell by checking pattern and rotating forward and back to see how everything is meshing. I am doing this daily so it is hard to explain on type.
