Hard tops with rear wiper and defroster were optional, but came standard with full-framed doors. Chevelle options included headlight washers, power windows and locks, and a rear defroster. Standard features were a cassette player, rear window defroster, and tilt steering wheel. Rear defroster was added to the options list while the tinted windshield became factory issue. On the dash are oversized levers that control the air conditioning, heater and defroster. Electric rear window defroster became optional this year, replacing the old blower type. Heater, defroster, and radio remained optional, as well. Every car was shipped with a colour-matching metal hardtop with a rear defroster. The defroster, always a popular option, was standard.
