A minor issue but: A little help please. I found NOS valve cover PCV tubes, but I am having a hard time finding the little curved rubber PCV hose that goes from stock air cleaner to valve cover. I have a repro that is supposed to be for a 67 Z-28 that I thought might work but the ID is way too large. Does anyone have a line on where I can look to find one, or two? (I have two Auto Therms that I have restored and want to have both complete.) A repro will do but I haven't been able to find one listed for my 69 RS/SS 350 with the Auto Therm air cleaner. I see them for BBs and Z-28s and Cowls and open elements, but not for mine. Thanks in advance!
