Safari Yellow. The 3rd generation Corvette was built from 1968-82, Running gear was carried over from the previous generation. The C3 design was based on the Mako Shark II concept car, it was longer, narrower and lower than the C2, it was the 1st Corvette to offer a T top and removable rear window. 1968 was the only year that used a push-button door lock below the door handle, it got 4 vertical slots in the front fenders and even tho it was still a Corvette Stingray, there were no badges to say so in 1968. In 1969, the 350 replaced the 327, Stingray script appeared on front fenders, now one word. Finger plate door release would actuate the door, eliminating the separate release button as in 68.
