I have a 1994 Hunter 33.5 with 2 inch white plastic "discs" mounted on the bulkhead with a small loop line used to hold and organize the sheet lines that run into the cockpit. Time and use have taken their toll and I need to replace them. I'd like to buy identical ones so that I can reuse the sizeable holes from the screw in each one but have been unable to find them. Does anyone know where I can source this type of sheet/ line holder? Thanks
