I need the hot air tube that connects to the underside of the 70-72 ram air cleaner and has the flex hose attached to it going to the heat stove. It's just a piece of plastic with a clamp on the air cleaner end and smooth with little ridges on the other. I don't know if it's different between the 350 and the 455 but, if it is, mine is a GS455. Anyone have a cheapie? Thanks.
