I am considering doing another run of stamped air cleaner hose with correct part number an AC with arrow. This is the formed hose from valve cover to air cleaner. 1970-72 The hose is available but not stamped. Very few cars have a correct stamped hose. I will see about ordering up a bunch of them if interest is here. All my yellow ink was gone so I ordered a new bottle. I am not going to do anymore Radiator hoses due to new ribbed rubber. It’s just not worth it. Cost of air cleaner hose will be $20 plus the cost of the hose. The pain in the butt factor is high on these hence the high price. Molded hoses are tough to stamp. Picture is my well faded original.
