I have to change the ignition system out and the nice mounting bracket that holds the current ignition box and coil and main wiring harness plug that bolts to the back of the head isn't going to work with the new system without some modifications. That got me wondering where these brackets come from to begin with as my current one was obviously designed specifically for the ignition system that was on it. Do the larger custom engine builders make them based on their ignition system of choice or ? I need a pair to hold a Crane HI 6M and matching LX92 coil. Thanks
