Harry, HONEYCOMB? In the late 1950's? I don't think so! The true honeycomb radiator went out during the 1940's. The stuff your radiator and heater core was made out of is still available. Any radiator shop should be able to remove the core from the heater core and replace same with new material. If not, find a shop that knows what they are doing. Just don't describe it as "honeycomb" when you talk to them. Bill W > After keeping my 57 Plymouth since 1981 I finally have it running and > driving on the road.
