New 9 tooth inertia starter for all Minis w/ inertia style flywheels used up to 1984. Post '84 cars had pre-engaged style starters and ring gears which used starter WC-GXE4527. Often engines get swapped around so it is best to simply use what came off of your engine rather than the year of the vehicle.
