Beeware that's the first I've heard of your car, very very nice!! If you have any more pics of it please post them. I've only heard of one real 71 black v24 duster before yours and it was the one Allen restored and painted a different color. When I first saw your car I was thinking it was one that was on Jacks Auto catalog and the orange decals were changed over to white but then I quickly remember that one had a vinyl top and it was not a real v24 car.
Black is by far my favorite on 71 duster v24 cars
