Sorry I misled you. I do have a std. cab. 1947 1/2 ton, 3100.

The two shades of brown metalli then were for deluxe cabs and the basic cab was gray? I'm confused because the data sheet online ONLY lists the two 'tan metalli-Chrome' shades for the interior. It doesn't refer to gray anywhere. Am I missing something? Investigating is fun but very frustrating that's for sure!!
