There are way for Dusters out there no doubt. But, if the parts do not move, then what.
The 66-7 B body rear qtr panels that have been out there are total junk. That crowd knows it, I bet if AMD cranks out some good qtr for those, they will sell! Different model, different crowd in general, different mindset.
But I agree, seems like enough Dusters out there that there is a good demand, maybe their sales experience says different? Dunno know.
