    Reproduction rubber grommet for the air conditioning case. This grommet encloses the tubes for the evaporator, and slides into a slot on the heater box. Owners with 1969 A/C please look at your existing grommet for the triangle shape like in the picture. Fits some 1969 Mercury Cougar and Ford Mustang (late built cars), and should be all 1970-73 Mercury Cougar and Ford Mustang.

    Replaces Ford part number C9ZZ-19B552-A.

    Check out our video below on how to replace a heater core! We used a '69 Cougar with A/C, but many of the same concepts apply to other years.
