If the new Pro-Cap doesn’t work on your application, these MSD Cap-A-Dapts will do the trick. The MSD Cap-A-Dapt adapts a large, Ford style cap onto your MSD distributor. This large cap spaces the spark plug terminals farther apart  which lessens the chance of cross-fire and ionization occurring. Spark plug style terminals are used on the cap for tight connections that will not vibrate loose.
