1966 Dodge D/Dart ~ 'Mystery, Myth and Misconception'

Unless you're referring to the cars Banning and Sons Motors received? Dave Reitz who drove for Bob Banning is still racing can be contacted. I would imagine he could tell you how many D-Darts they had.

I believe there is ones claimed to be here in the Battle Ground/Vancouver Washington area. I have not seen said car only heard of it being under restoration locally through the grapevine.
