I have this very issue to contend with in the near future. I am not confined to the champagne interior color that is standard for those years, but I am very undecided on what color would look best for a custom color. The outside is a sports car yellow with black accents like the frame accents in the pics in the Bolt Bucket, but interior? No idea. The grille and glovebox will be stainless as well as the standard deluxe cab stainless kit, but what to paint the interior? Medium to mid-dark gray maybe with black steering column? I am not an arteeest!
