stripe

Holmes is right. There was no "GT Swinger". Besides the stripes there were other appearance differences between the Swinger and the GTS (or GT Sport). The GTS was the top of the line model with the upgraded interior shared with the GT. The Swinger had the interior shared with the base model Dart. The GTS had a blacked out grille shared with the GT, the Swinger did not. The GTS had a trunk finish panel shared with the GT (except for the GTS vs GT name badge), the Swinger did not. The GTS had wheel lip moldings, and rocker moldings. The Swinger had neither and had no side trim at all.
