Dose anyone know how to determine the original color of car with a __ ?

Thought I read somewhere that was a special order color, something other than the listed colors.
Might be on build sheet if you can find it.

Other than checking the overspray, I think you might be SOL.

ya that is special order and I suspect without some sort of original documentation or as was sugessted some overspray or some orginal paint left somewhere on the body you might just be SOL.
