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 chances of cross-fire and ionization occurring. Spark plug-style terminals are used on the cap for tight connections that will not vibrate loose.
The Cap-A-Dapts will install on most MSD Pro-Billet Distributors (except the Ford FE). Kits are supplied with a high quality cap with brass terminals, rotor and cap spacer.

Rotor is injection molded out of DuPont Rynite for incredible strength and resistance to spark. Thick vanes are incorporated to stir up the air in the cap for even more ionization prevention.
