Reproduction 1963-1976 Windshield Wiper Washer Hose Cowl Grommets Pair. These are the two grommets on the cowl of your Corvette that the windshield wiper hoses pass through. The wiper hose goes from the washer pump to the actual windshield wiper arm washer sprayer head.
The grommet produces a correct seal at the cowl and keeps the hose from being abraded by the fiberglass opening.
