It would be interesting to see how the switch attaches to the shift linkage levers on the steering column.
So it could be adapted to fit a 1954 Chevrolet panel truck.
Just have to figure out where to put the back-up light.
Only the switch itself is the same, the mounting bracket and lever are different. The switch bracket clamps to the steering column, and the lever clamps around the shifter rod, and is adjusted so it only closes the switch when reverse is selected, as it can catch it in 2nd if out of adjustment. I'll see if I can get a good picture of the one in mine. It's slightly altered from how it is supposed to mount, as the column clamp had a bad weld on it. I had to attach it a little different, but the operation principle is the same.
