This distributor rotor is also used on other IHC powered equipment and power units.

Important information below, please read.

This distributor rotor button will ONLY fit the ORIGINAL IH Distributors that are typically mounted horizontally.  There were various aftermarket replacement distributor assemblies made for International Harvester engines.

Due to the various internal differences from the original IH distributors this ignition distributor rotor button can NOT be used in aftermarket replacement distributors. Externally the aftermarket distributors may look almost identical to the original IH distributor but they have different internal design tolerances.

The last photo shows where typically the part number is cast on the outside of the housing on an original IH distributor.  If your distributor has no part number cast in the base it is most likely an replacement aftermarket distributor.
