And I run 2 bearings with the bevel, which are more susceptible to damage, so just as personal preference I would recommend just regular shimming on the bevel, and then accordingly adjusting the motor height.
You won't really come off any worse?
Then again, I'm just a perfectionist.

If you shim the bevel gear away from the motor gear, it'll cause the motor gear to not mesh properly and cause it to slip off. I only mentioned it because of experience, not because of any theory. One thing you should know about me, I mostly speak from things I've seen, that is my opinion based upon experience and from having to fix and upgrade many dozens of guns over the past few years. I'm not just picturing things in my head, I'm actually saying what happens in most cases because I had to unfuck many guns. Under the bevel it's either a very thin shim, of no shim at all. There is no guide for this, it's all based upon the parts at hand, the gear type, bushing type, mechbox type, etc. Everything has to be custom setup based upon what the system is. No guide will give you everything you need simply due to the fact every manufacturer has different tolerances.
