Next the tricky part, use a nut/bushing from the headlight switch. Order a 7/16"-28 tap, I got mine from McMaster Carr, about $11 plus shipping, I think the total was around $20. Remove the plastic bushing inside BEFORE you drill it out, it will cause you problems and theres not a lot of extra material. Drill the center of that out with a 25/64" drill, then tap 7/16"-28. BE CAREFUL, it is close, and there is not a lot of extra material, but it does work.
