hmmm, kinda what I said, except the Duco paint chips for 57 show the light gray as Marble gray [as Tim cites for 56] w/ the number being 73604, and lists no # for the charcoal!
"commonly painted black"? I've seen a lot of unmolested TF trucks, and never seen any that was 'black' on top the dash, but the charcoal color the factory used does start looking like faded black after 40 years or so, and I can't imagine that flat or eggshell finish they used would give any glare, whereas gloss black definitely would
on this truck the column, shifter, pedal arms, wheel and hand brake are the original charcoal - the pedal arms and hand brake 'look' black, but are the same dark gray - the rest is my choice
