    FAQ

    What type of distributor does the MSD 8406 kit fit?

    GM distributors using an external coil, with a screw-on style cap.

    Why should the cap and rotor be replaced together?

    Both are maintenance items, and replacing them as a set (like an oil and filter change) keeps the ignition system reliable.

    What color is this kit?

    Red.

    Does this fit a stock distributor?

    Yes, it is designed to fit the stock distributor.
