Hey everybody, about three months ago, I bought a 1990 Macgregor 26s, and the furler drum needs a new top plastic peice in order for it to properly function. The furler is a CDI Flexible Headsail Furler FF2. So far I have only been able to find the entire furler for sale, but I just need that one peice. Any thoughts on where I could get/order one?
