’68 was another year of Corvette for major remodeling. The fast back was replaced with a tunneled roof coupe. It had a removable rear window, and a two piece roof, called a “T Top”. The front was more aerodynamic, and the headlights were hidden as usual, though they were now vacuum operated instead of electrically. Chrome was eliminated from the sides, and the door handles were replaced with push buttons. 80% of the models were 4 speed transmission and had tinted glass. Top speed was 142, and the L79 could go to 60 in 6.3 seconds, while the L71 only did 7.7 seconds.
