The Corvette received its first major body redesign in 1956. Only the instrument panel remained the same. The new design featured roll-up windows and power assist optional. External door handles and locks exposed headlights and the famous side cove. This was also the first year for two-tone paint, seat belts, factory hard tops, and the 1956 Corvette was the first car to offer a "Transistorized" AM Radio, and "Dual Point" Distributors. Dual four-barrel carburetors were available as an option on the V-8.
