MSD 8420 Cap-A-Dapt with adjustable rotor.
Fits most MSD distributors (Except 8594).

The MSD "Cap-A-Dapt" will fit a large Ford style cap onto your MSD Pro-Billet distributor. This spaces the spark plug terminals farther apart to help eliminate spark scatter inside the cap, and reduce cross-fire, and ionization. The adjustable rotor enables you to fine tune the rotor tip to cap alignment so that you can adjust the rotor phasing. This can be very beneficial if you are running a Multi-Step Retard or Timing Controller.
