What 1950s Chevrolet vehicle was inspired by the ford ranchero and was considered a car-truck hybrid?

You would be thinking of the famous Chevrolet El Camino, which was Chevy's answer to Ford's Ranchero. It was in 1957 when Ford brought the Ranchero (a Ranch Wagon with the cab sliced off) to the world, and two years later, Chevy joined the party with its Bel Air-modeled El Camino.
