I thought Deluxe Interior got you the door panels, set covers, and carpet on sides in the rear? I thought wood grain steering wheel and wood grain dash were some other add on? Then pedal bezels not sure about those? Just like Formula S didn't get you the 150 speedo that was an extra cost option. Then in '69 they decided to make fold down rear seat on fastbacks extra cost option where as previous years was standard. Maybe original sales brochure, which I don't have, could shed some light?
