This Powerforce™ 7.5 inch harmonic balancer features a supplied timing pointer that fits where the stock pointer mounts. This allows you to use this damper in place of your stock 7 inch damper. Also includes a “V”-grooved pulley for the alternator belt to be used as is for a one-belt application.
For engines prior to 1968, you remove the supplied pulley and (using the supplied spacer) bolt your pulleys onto the damper.
