Concours correct red striped heater hose for late 1968 (after 2/1/1968) Mercury Cougar and Ford Mustang. Durable red striping with "Autolite" spelled out and dated H8A23B. Correct for all V-8 engines without air conditioning. The difference with the 'with air conditioning' hoses is they have a molded 90 degree elbow. Some length trimming may be needed for a tight looking fit. Turn those hoses so that the red striping shows!
