The Factory discharge hose used on the 1968-72 Cutlass, 442 & F85 with factory air-conditioning had a molded muffler insulator. Our standard hoses include a functional insulator which does not have the factory appearance. We are now offering a molded insulator for the original appearance. Contact us if you would like your rebuilt discharge hose to have this insulator installed. This does not include any of the hose assembly or muffler, only the molded foam insulator.
