Hi All:I want to convert my auto inflate SOSpenders from Auto inflate to manual. And, while that is a straight forward process, trying to purchase just the little green inflator pin has become a major project. West Marine will gladly sell me a complete rearm kit for $30 which includes the green pin, but I cannot find a source for the green pin only. What good are the spare CO2 cartridges that come with the the SOSpenders if you have to buy a complete rearm kit which includes the cartridge ? I did find a kit that included only the bobbin and the green pin, but for a manual conversion, I don't need the bobbin either.Any sugestions ??Thanks....... Jeff
