Yep, that's mine. I've still got the shell, but it is a factory black '70 Duster with red bench interior, fold down arm rest. /6 auto. Too bad the frame is rotten.
I hate to say this but im really starting to think your duster and mine are the only 2 that exist..everytime i google factory black on red duster,it only brings up your car.i cant find pics no where on the net of any.
