Hey i just put a 16" track under my zx chassis and now it is ratcheting. So im trying to find some 9 tooth extroverts to put on it. Does anyone know if the axle for a zx it 1 1/16" or 1 1/8". Also can i fit drivers from a 1 1/16" axle onto a 1 1/8"? By the way if anyone has any extra drivers i would love to take them off your hands.
