The 1966 Furys kept the same profile as the 1965s, with a split front and rear grill motif. For 1967, the body was restyled with a sharp, angular profile. The stacked quad headlight bezels were curvier and set more deeply into the body, giving the car a more muscular look. The roofline had sharper angles and gave the car a longer, more luxurious appearance. A new, formal two-door hardtop body style appeared which featured smaller rear quarter windows and a wider, back-slanted "C" pillar. Called the "fast top", it was offered alongside the restyled thin "C" pillar hardtop in both VIP and Sport Fury series (as well as on corresponding big Dodge models). The 1967 model year introduced new safety regulations, which meant that for the first time, all Plymouths included dual-circuit brake master cylinders, energy-absorbing steering columns and wheels, recessed instrument panel controls, and shoulder belt mounting points for outboard front seat occupants.
