(chain

I scored a complete running 70's sears roper mini bike...Its looks to be a two speed as there are two sprockets side by side on the clutch output shaft. I dont have either chain. I also need the drive chain that goes from the torque converter to the rear sprocket. Does anyone know what size...

What size thread are the holes near the shaft on a clone?:shrug: The ones where you'd bolt on a chain guard or whatever... Thanks-
