Packages available for the 1967 Model Year: Standard Hardtop, XR7, GT, Dan Gurney Special 1967 Mercury Cougar Standard The 1967 Cougar was based on that year’s new second-generation Mustang, but with a 3 inch (76 mm) longer wheelbase and new sheet metal. A full-width divided grille with hidden headlamps and vertical bars defined the front fascia—it was sometimes called the electric shaver grille. At the rear, a similar treatment saw the license plate surrounded on both sides with vertically slatted grille work concealing tail lights (with sequential turn signals), a styling touch taken from the Thunderbird.
