These breaker points fit the Autolite (Motorcraft) distributor used on the Ford 1600cc "Kent" OHV engine. Note that the 2.0L SOHC "Pinto" engine distributor rotates clockwise (opposite of the Kent) and requires different points.
If you are not sure if you have a Bosch or Autolite distributor, measure the diameter at the base of the cap. A Bosch cap measures 2.87" in diameter. The Autolite cap measures a 3.35" in diameter (excluding hold-down tab protrusions).
