I had these once on a boat that I sold and needed more, I called the factory and told them that I needed more for that reason and the lady asked for my address and sent me some free of charge. Done the same thing a few years later and they just laughed at me and said that it would be $45.00 for new ones. Amazing how a crappy economy does for customer service. Awesome, flatoutally, thats what I call helping a brother out!
