Here's a photo of half a spark plug used to create the external coil wire terminal. The hard part is removing enough of the innards to solder a piece of wire from the metal post in the spark plug to the flat spring terminal that goes to the cap.
A guy named Alvin from Georgia sent me this with the following instructions:
"The spark plug could be moved to the side or top to get more fan clearance. After cleaning out the coil can I lucked out and still had the wire for the points spring attached, I spliced with a wire long enough to extend about 2" higher than the top of coil can with a eyelet on the end. Put spark plug in lathe and removed all metal only leaving porcelain. Broke away part covering the electrode. Soldered a wire with eyelet on end. Drilled out rivet holding hi tension bracket to bottom of coil. This left a hole just right for a 6-32 screw thru bracket, thru bottom of coil, thru wire eyelet and nut on inside to make connection and hold every thing together. Drilled hole for a tight fit of spark plug to prevent leaking when filled with black 2-part polyurethane potting material. Only takes about 15 minutes to set up."
