Not sure about gear pattern. I am changing the ring and pinion in my camaro to 3.73s. To me this gear pattern looks pretty good. I was wondering if some of you guys that have done them could take a look and let me know what you think! Thanks and hope these pics can help.
Also i did this with the old bearings on the pinion(grinded them to slide on and off) with no crush sleeve and the nut just tightened down to pull the bearing into place and keep the slack out. So i still have to install the pinion with the crush sleeve and torque it down. Will this change any patterns? I am trying to avoid having to use a bunch of crush sleeves and press the bearing on and off the pinion.

Your pattern will change when you go to the new bearings for the final install. I did the same thing when I built my 10 bolt. The change won't go from a good pattern to a bad pattern but there will be a difference. If you want consistency it's best to modify some new bearings so they slip fit for setup work then use unmodified bearings for the final install.
The switch from used to new pinion bearings completely messed up my settings for the solid pinion spacer.
For myself I will never use old bearings as set-up bearings again.
For the gear pattern to stay the same from set-up to final install you have to torque everything to spec when checking the test pattern. This includes the carrier cap bolts and snug the pinion nut down till you get the correct rolling drag on the pinion, IMO otherwise you'll end up chasing your tail when the pattern keeps changing.

Yes, there is no need to use a crush sleeve during setup. Grind the self-locking feature off the old pinion nut so it spins down by hand and use that for setup, but do tighten the pinion nut so that the rolling torque of the pinion is correct.

Yah i have the nut grinder. I just tightened it so there wasn't play though. Didn't think it was necessary to get it to the right rolling torque

Check out this R&P install guide from Yukon Gear, it's very informative.
