I just bought a rust free naked '54 cab. There is a hole on the left side of the dash several inches above the headlight switch. It appears "not factory" to me, but I just saw a '54 on E-bay and it has a switch/knob in the same place. Is this a coincidence or was there a factory item that was available for that spot? My original cab, which is a 55/1st has no hole in that area.
