From Ford press: The Thunderbird grew a little more when the 1967 models were designed. Overall length was 206.9 inches (1.9 inches more), and it seated six. The 1967 Thunderbird represented one of the most dramatic styling changes in industry history. It was a jet aircraft-like design featuring a long, thrusting hood and a short rear deck.
The front-end highlight was a crisp latticework grille deeply inset and outlined with thin, bright metal moldings on the top and sides. The grille was framed at the bottom by a new deep-sectioned bumper that blended into the sheet metal, and the headlights were concealed by the doors and the outboard edges of the grille.
From 1967-69, a four-door model was produced and rapidly gaining value in the collectors’ market.
