The SPD of the vehicle is 820 being one of the last 72 Duster340 cars to roll off the line. I thought it strange that this late build 72 would have cutouts for the rear spoiler option...very strange.
Another interesting item is the lack of the seat belt warning light on the dash just below the headlight switch. This indicator was found on a couple of my earlier 72's with SPD'S of Jan & March.
