Rarest A-Body Option?

Well, I think a 1972 Dart with the optional 340 would be pretty rare. There were only 50 made and very few of them survive today.

Canadian-only '71 & '72 Swinger Special 340's ! Yea ! I'll gladly take one of each year ...

I was in contact with a gentleman from Canada whom had a friend who was restoring an FY1 1972 model , down to its correctly-painted motor and air cleaner :toothy2: .
