1961/62 & 1963 Uni's w/o side mouldings.
The tu-tone paint was divided along the scallop line that runs thru the cowl, door and quarter panel to the taillamp.
Many 1961/66 trucks were tu-toned with the secondary color being white.
Following that scheme: Yellow roof, white above the scallop line (inc. all of the hood and the door's window frames), yellow below the scallop line.
If a 1963 with side mouldings, I'm not sure how the tu-tone paint was divided. I have factory photos of tu-toned Uni's w/o side mouldings, none with.
Note: Uni doors have a straight thru scallop line. Non Uni doors have a scallop line with a "dog leg."
