Does anybody have the correct Part Number for the rubber grommet that is in the top cover of the air cleaner. The grommet holds the black plastic tube in place. There is a hose that comes from the valve cover that goes on to this black tube. The part number for the hose is A6170180282. I have gone to 2 different dealers and the part numbers and parts they show are wrong. The part they have has an inside diameter of about 3/4 inch....it should be about 1/2 inch. My car is a 1985 300 CDT and has federal emissions and was bought in Germany if that matters. I am the second owner...the first being my sister and it is still all original.Thanks for any help.
