On the 1946 Panel and Suburban with barn doors, I can see where they have notches on the passenger side rear doors for electrical contacts. I also see where they have the cutout with the plate for inside access on both doors. Would this indicate that on right-hand drive trucks, (from down-under and across the pond) that the taillight was on the right rear door? And if rightly so, would it be inappropriate to mount a second taillight on the right side? Has anyone seen a truck with barn doors with two taillights? Could this have been an USA factory or dealer option?
