Hello all, For those of you with aluminum goosenecks like ours, I took the suggestion from Joel and Graham, and found bronze bushings at our local ACE hardware. I then drilled out the 1/2" hole to 5/8", and pressed in the bushing. One bushing was a tiny bit loose in the aluminum, so I mixed up some thickened epoxy to ensure it won't move. There were stainless washers, and I'm going to go with nylon, at least on the top and bottom. FYI, I found very little wear in the hole where it attached to the boom, the wear was primarily in the lower hole at the bottom of the mast bracket.
Hope the picture helps. https://www.dropbox.com/s/w5iixd3ooltio77/Gooseneck%20fitting%20with%20bronze%20bushings.jpg?dl=0 Bruce Whitmore 1994 C&C 37/40+ "Astralis" Madeira Beach, FL
