The Gold Duster has the fold-down rear seat option, so in addition to the molded floor pieces, we also need some extra 80/20 pile carpet to do the rear seat back, trunk divider, and the flat platform behind the seat.
Legendary does list a fold down rear carpet kit (loop or pile) for the rear seat on the space Dusters, $95 with a 4 week wait. I called and it does have the correct bound edges like the originals.
