Detailed Description

The Standard Ignition RX-89 alternator brush set is used in alternator and generator-related charging system service where worn brushes can reduce output or interrupt charging performance. This part number is listed for a wide range of 1962-1964 vehicles, including Chevrolet Bel Air, Chevrolet Impala, Chevrolet Corvette, Pontiac Tempest, and Oldsmobile 98 applications.
