I reserve the tire iron for those who butcher restorable trucks (and threaten to paint them lime green

). From the description on Coach's page, this truck is an engineering feat with a Chevy pickup around it.
Coach, I have no idea how to rearrange the wiring so your starter solenoid is switched, or even if that's how it's supposed to be. I would recommend replacing the starter solenoid and the points (if you're using points ignition); it can't be good for the ignition hardware to carry a charge long enough to bleed the battery.
