Concours correct red striped heater hose for Mercury Cougars and Ford Mustangs built prior to 2/1/1970 WITH factory or integral air conditioning. After 2/1/1970, the red stripe and date code was changed to yellow. Durable red striping with "Autolite" spelled out and dated H0A12A. Correct for all V-8 engines with A/C. Theses hoses have a correctly molded 90 degree elbow on one end that attaches on the water valve side. Some length trimming may be required for a tight looking fit. Turn those hoses so that the red striping shows!
