I recently purchased a 1970 Sunfish in very good condition except that it is missing the brass/bronze plug for the bailer. I have been unable to locate a replacement plug but saw on a thread that a plastic plug from a hardware or a farm supply store would work. I hate to spend $40 and the time and effort to upgrade to the current bailer. Does anyone know what size threads are used on the old style plug (cap)?
Since I was unable to find a threaded stopper I tried a synthetic cork from a 1.5 liter wine bottle (I think it was Australian) and it fit perfectly. It was snug, long enough to get a good grip and being synthetic is stronger than natural cork. When I mentioned this to friends, I got several donations. I don't drink much wine, so I don't know if the regular 750 ml bottle corks work.
