MSD Part #7403
MSD distributor caps and rotors are designed with performance in mind and molded from high-quality, voltage-insulating material with terminals that resist carbon tracking. Whenever the distributor cap is changed, you should install a new rotor. Likewise, if you're replacing the rotor, be sure to install a new cap as well. MSD has new kits featuring Rynite injection molded distributor caps and retainers to complete your distributor tune-up. MSD also has Cap-A-Dapts to fit large Ford-style caps onto MSD distributors.
