I seem to remember on some earlier articles of yours that Ford eventually made all the coils tractor units?

Larry... The first run in early ones were embossed as tractor units, had a few myself in past years...... The capacitor was physically wider than in other other Ford made coils , and the potting tar was of a higher melting composition.
