The Chevrolet C10 was a variant of the 3rd Gen C/K that was introduced for the 1973 model year. The C10, which was a 1/2 ton, rear wheel drive pickup truck, was offered with a wide range of engine options. These engines included inline six, V6, and V8 units whose power ranged from 105hp to 230hp, with drive sent to the rear wheels through manual or automatic transmissions. The 3rd Gen C10 was available in two bed configurations, with the sleek Fleetside bed, or the fendered Stepside bed being the two options. Notable trim offerings included the Silverado and Scottsdale. For 1987, which was the final year of 3rd Gen C10 production, Chevrolet changed the name of the C10 to the R10, in order to avoid any possible confusion with the forthcoming Fourth Generation Chevrolet C/K.
