Not home right now, but all I did was take the cap off and line up where the center of my coil was based on where the cap sits. I then drilled the hole. After drilling, I covered the new hole w/ box tape on the inside of the cap, and the same with the old hole on the outside. Spooted a couple drops of epoxy to the inside of the old hole.
The tape outside will create a mold for it to set in, while the tape on the inside will keep the epoxy out of the new hole. Let set overnight, remove outside tape, clean inside to be flush using a small dremel grinding stone.
