Roedel Bros LLC.

Remanufactured vacuum advance diaphragms for IH light trucks equipped with either points or the Prestolite or Holley electronic ignition systems.

Please selection the correct version for your application. NOTE: If you have either the Holley electronic, or curved or straight points ignition, you can determine which is correct by looking at your current unit and determining if the arm is curved or straight and what degree you need (i.e. curved and stamped with '5' for example).

Remanufactured in the USA.
