1977 Corvette Production Information

Leather seats were standard for the first time in 1977, cloth seats inserts were an option. The anti-theft key switch was removed, and the side flags were added. The 500,000 Corvette drove off the assembly line in May. Former GM Chief Ed Cole died in a light plane crash in Michigan. Bill Mitchell resigned from GM in July and Irv Rybicki became the head of the GM design staff. The mid-engine V8 Aerovette was shown for the first time.
