So i got the optional 72T spur gear but with that gear there isn't holes in it like the stock 87T gear so I cant get to the back motor mount screw to tighten it down? I thought about drilling a hole in it to allow myself to get to the front motor screw, but Im afraid it will need to be to close to the actual teeth of the spur and it will weaken it. I see there is another screw hole that lines up with the bottom screw on the motor. Should I be just using the front and bottom screw? Or is there another solution I'm not seeing to be able to tighten the back motor screw?

Thanks in advance for the help.
