I have a 2004 Hunter 33 and the spools or drum of my Lewmar Genoa cars are chipped. These are large chips about 1/4 to 1/2 inches. I want to replace the cars but am not sure which size to order, Lewmar lists there sizes by Ocean size 0-4, I believe I have size 1, can anyone confirm? The second question is can I use another manufactures’ car like Harken on my Lewmar track?
