When changing the 84 Bronco II to a duraspark ignition I've learned that when I ordered a distributor, Advance Auto part#30-2691 (single vacuum line) it doesn't come with a cap adapter to fit the larger cap. Advance doesn't list a cap adapter for that distributor. The cap adapter part # FR109 which fits about 20 other fords, will fit #2691 distributor. Along with those you will need a rotor#FR106 and a cap#FR121. The distributor and cap adapter both had to be special ordered.
