Dear Bill I have done a little research. I bought an old original "Truck Data Book specifications catalog for Chevrolet Salesmen". On the Cabs and Bodies page;Interiors it shows your truck with the plaid panel inserts in the doors and the dark dashboard top. The copy says "The instrument panel is finished in handsome charcoal and silver-beige enamels, with the crown of the panel having a glare proof crinkle finish. Blue or green enamels replace the silver beige finish in Custom Cabs when blue or green upholstery materials are used." In your photo the dash is a dark color is the entire top of the dash crinkle black or somehow just the crown of the dash above the instruments? Also what color is the rest of the dash panel. Thanks for the help I am really trying to keep to stock finish layouts.
