Gutted the original 37 coil to get it ready to slip over a 12 volt coil and cut off the conduit from the original ignition switch,hated to do it but a couple of the original parts will be going back on and will fill up a hole in the firewall. I was hoping I could use the original ignition switch since it will be going back to the foot stomp starter but I wired the truck for a ignition switch with a accessory post.
