Brand new Inertia starter motor with the correct 9 tooth pinion for all Classic Mini cars up to the fitment of the pre engaged type in 1984/5. Do not fit the 10 tooth starter sold by many as it can ruin the ringear or the bendix. Other Leyland cars used 10 teeth such as Sprite, Spitfire and Mini Metro and often get fitted ass they are cheaper but 9 teeth is rarer to buy but is meant for Mini 107 teeth ringears
