'73 CB350 igniter box bracket

Installed Probe Engineering BT-05B electronic igniter box, showing access to timing curve adjustments. Trimming the stock rectifier bracket from the battery box allows the igniter box bracket to sandwich between the battery box and the starter relay bracket. We replaced the stock regulator and rectifier with a combined unit that fits where the stock regulator normally mounts (see bottom left of image).
