Restoration Correct Original AC Delco Part Correct Fit And Finish Fits V6 And V8 Engines Also Fits Trans Am 85, 87 Made In Usa When chaning the distributor cap on your 1982-1987 Firebird, did you loose the Distributor Cap Brush? No need to buy a new cap for just that small part. This rotor is pressed against a carbon brush on the center terminal of the distributor cap which connects to the ignition coil. The rotor is constructed such that the center tab is electrically connected to its outer edge so the current coming in to the center post travels through the carbon point to the outer edge of the rotor. As the camshaft rotates, the rotor spins and its outer edge passes each of the internal plug terminals to fire each spark plug in sequence. Don't trust just any parts on your 1982, 1983, 1984, 1985, 1986, 1987 Firebird.
