Only minor styling changes occurred from the 1975 to the 1978 model years, most notably, during the 1977 model year when quad stacked square headlights (see photo) replaced the previous round dual beam headlights, the front turn signals, previously on the outboard edges of the grille, were moved over to the cutouts in the front bumper. Tail lights received amber turn signal lenses in place of the previous red turn signal lenses. Various 2-door models had no centerposts and some of them were true hardtops with roll-down rear windows. Other two-door models had fixed rear windows even though they had no centerposts. For the most part, the Plymouth Fury two-door models, during the 1975 and the 1978 model years, were labeled as "hardtops".
