Dang! This is tough.
Other memories come rushing in while trying to decide:
The Max Wedge Engines.
Triple spinner hubcaps on the 1964 Sport Fury.
The overhead console on the Challengers.
The dual snorkel hood scoop.
The Shaker hood scoop.
The Air Grabber option.
The Hemi billboards on the Cuda.
Arrrgh.
