I'm in a rare moment of agreement with Phil.
The three that should still be more or less intact are the Lancer, Newport Convertible and the Fury Coupe. The Imperial is too clunky by half, and the Dodge Dart 440 4-door got mauled to make "Dodge Revellion" (which could be an amusing re-release)
Would be no trick to make them a "California Wheels" type of restomod - and kick the stock stuff to the curb. Or somehow truncate the reverse side of the stock cover, and create a drop in 'sleeve' that would integrate with one of their current choices.
You take them for what they are... charming, crude, fun. Let the kit bashers have at them.
