M_Boats: Rudder Printles for '81 Monty 15

Hello All: I'm getting my '81 Monty 15 ready for sailing and want to make a mast carrier that mounts to the rudder gudgeons. I measured the pintles on my rudder and the pins are 1/2" in diameter and about 1 3/4" long. I don't want to replace currently installed pintles or gudgeons if I can help it to get a matching set of pintles and gudgeons. Does anyone know where I can find these pintles or something close that will work? Looked on the internet but choices I found were very limited. Maybe I am just looking at the wrong websites. Best Regards, Mike Hall M15 #167 "Dreki" Tustin, CA
