Hi Zack,....nice job !!.............from the overhead shot it appears that your pinion is only running on half the spur......any flex in the motor pod/axle uprights can lead to gear mesh issues/failure.......I have seen this often, it is not uncommon, particularly in a proxy series where the cars run many many laps with no adjustments made.....the wheels/spur will tend to move slightly, increasing lateral movement of the rear axle, and if this happens,......on left hand corners, you will have issues.
As a general rule, even if the pinion is 5/10 thou. proud of the outside face of the spur. you are good to go.
Cheers
