Swapped to Muscle - 75 Duster Daily build

While your looking into the wiring and the dash is out, you might want to look into how the seatbelt interlock is connected/bypassed. It only allowed the starter to operate when the seat belt was latched. I thought it was a '74 only thing, but that little box with the red button by your HEI module looks like part of the system. Been so long, but I remember at module under the dash that I removed and connected two wires.
