We rebuilt our Autolite breaker plate using bushings from a new Motorcraft plate. This way, you get the steel pivot and retainer for reliability. The only part that wears out is the nylon rub bushings between plates. Replace them and you have a new breaker plate. Note that the best modification you can make to a classic Mustang is the PerTronix Ignitor II, properly adjusted with the 0.030-inch thickness gauge provided in the kit. Do not forget to connect the stray ground wire, securing it where the condenser was. This wire grounds the floating breaker plate and the PerTronix Ignitor II module.
