3.73. The Windsor made up 64.72% of Chrysler's sales. For 1956, the "Forward Look" restyling came out, introducing the first tail fins on a Chrysler car. Interior trims remained mostly the same, though a new Highway Hi-Fi phonograph player was a new option on the Windsor. The 1956 edition for the Canadian market featured the Plymouth 303 Poly V-8 Engine, the same one used in the Plymouth Fury and the Canadian Dodge Custom Royal. 1957–1958 For 1957, Chrysler cars, including the Windsor, were restyled again. This time with taller tailfins with vertical taillights, thinner C-pillars, and a wraparound front bumper. Mid-year, dual headlights became standard. Front head room grew to 35.7 inches. Safety equipment was optional on the Windsor.
