I was certified back in about (I can't find my card) 1973- 74. I purchased my calypso regulator back then and need an exhaust valve for it. I found a part number (105139) and thought that was what I needed. But that valve is way too big. That valve was about 30mm wide and my exhaust port is only about 22mm wide. Does anyone know where I can find the correct part number and part? I will thank everyone who responds in advance and thank you for your help.
