I changed my rear pinion gear to metal now the motor mount won't go all the way back. I tried several times... Any Ideas where I'm screwing up?
 
What tooth was it at and what tooth is it now?

Is the motor screws preventing the motor from moving?
 
I replaced it with stock gears 37/13 Hot Racing . Motor spins fine by itself. It's just when I slide it on the pinion it dosen't want to go all the way back. I don't get it..
I'm gonna pull the motor mount off and see if it's bent.....
