I need to replace a couple of the plastic levers that release and secure my halyards. The clutches on the boat now are made by easy lock. I have checked a couple of marine suppliers and they can't find an easy lock. Does anyone know if it was original equipment on the 1978? Or has anyone had to replace similar parts without replacing the whole clutch. It works just fine and I don't want to spend the $150 to replace them. Thanks,
