If you are building a 1982-2003 hardtail Sportster chopper using a TC Bros. King & Queen seat, Cobra seat, or rigid Solo seat, this part will make your life much easier. Sportster chopper builders often struggle to find a good place to hide/mount the OEM Ignition module on hardtail frames. This TC Bros. Igniton Module Mount is CNC Laser cut from aluminum for a precise fit to the underside of the seat mounting brackets that we sell (106-0079 & 106-0080). Simple and effective, this mount also has slotted holes pre-cut to the spacing found on the OEM Ignition modules. The included hardware insures that installation takes very little effort. Proudly made in the USA!
