Standard Ignition Distributor Cap Adapter P/N:FD-166
Keep your ignition system firing cleanly with the Standard Ignition Distributor Cap Adapter (FD-155), a direct-fit replacement for many 1974-1986 Ford and Mercury vehicles. A distributor cap adapter provides the mounting interface that secures the distributor cap to the distributor, keeping the cap correctly located over the rotor so the ignition can distribute spark reliably. Confirmed applications include the 1980-1986 Ford Bronco, 1977-1986 Ford F-150, F-250 and F-350, 1977-1986 Ford E-150, E-250 and E-350 Econoline, 1978-1983 Ford Fairmont, 1979-1982 Ford Mustang, and 1980-1982 Mercury Cougar — see the Buyer's Guide tab for the full list of 34 applications and engine details.
If a cracked, worn, or ill-fitting adapter is causing your cap to seat poorly, this replaces it. Always diagnose an ignition misfire before replacing parts.
