Won't the spiral teeth on the gear keep it pushed up against the bottom of the distributor housing with the engine running? I would probably add a thrust washer between the gear and the housing to reduce the end play a little, but in the real world, it's probably a solution looking for a problem. I'd be more concerned with the vertical position of the reluctor and the pickup coil teeth.
