In 67, where did they put the reverse switch? I also wonder if I could install one? When I got the truck, it had the cutouts in the back for the lights, and a wire from the harness to each empty hole, and this funny little tab at the base of the stick shifter just inside the cab with a green wire sticking up through it. So I figured it used to have one that the previous owner removed along with the tail lights. I have the lights in and the wiring in place up to the tranny....just need the switch
