LemonHead, there is an active Chrysler message board, with about the only info on the Starwinds that I have been able to find on the web. Worth checking out once you get everything back to normal at home. I also have lots of pictures and plans for the swing keel brackets and pin.

I'm not a member, but I stalk that board on occasion. I have a small collection of info on the starwind (dimensions, C22 manuals and info, photos of other Starwinds, etc.) but I don't have anything on the swing keel. I'll PM you my email address. I'm building my own manual, bit by bit. It takes a lot of digging to find detailed info on these boats.
