The early 1210's had a coil ignition the later tractors had the Mag12. You'll most likely need to use the ignition switch for an early tractor and may need to do some wiring. Pretty sure Roland can hook you up with the wiring diagram. If you go to the Cub parts site lookup you can check what switch you'll need. Scroll down till you get to the place to enter your model # and enter 1210
