How many of those among this forum have seen --let alone heard of --the 1971 and 1972 Dart 'Swinger Special' 340 models ?
There were special order 340-powered , base model Dart Swinger hardtops , sold at two Western Canada dealerships : Crosstown and Crest View, located in Edmonton, Alberta and Regina Saskatchewan. http://phscollectorcarworld.blogspot.com/2015/02/ghost-cars-1971-72-dodge-dart-swinger.html
A friend of mine is currently restoring a gorgeous GB5 1972 model ( another 1972 model has been restored ; an FY1 model ) --- here's a photo of it and its present state-of-restoration .
Note it barren appointments : colour-keyed rubber floormat ; no radio (note blockoff plate) ; base steering wheel ; and , not seen here ; no rear arm rests . Also , no power steering , and no power brakes ( 4 wheel drums ) . The black "Bumblebee" Stripe is a dealer-added embellishment .
Few were built , and few remain .
