Gents,
I'm unaware of what is on other boats but on Wildcat, if the pintle is bronze it has been plated.
So... with a set of calipers, check the size of the gudgeon hole and mike the pin size. The pin can be re-plated to build up the OD. After plating it can be ground to size. Likewise, the ID of the gudgeons could be filled with weld and re-sized (though I would be concerned about heat distortion on such thin material)
If it were my problem, I'd have the gudgeons cleaned up (oversized by .010 or so) to insure they are round and then re-plate the pins and have them ground .005 under the new gudgeon demension. Most any local machine shop should be able to help here.
You don't have much material to work with on the existing gudgeons. If you are making new, I would suggest making the gudgeons oversized and then bushing the holes with a .500 or 1.000 long bushing to give more surface area and something that can be replaced when necessary.
