imo you should contact the local dealer. ablw womack is listed as your local raymond dealer. (877) 989-9570. if you have the model and serial number for the truck they should be able to get all the parts your looking for. make sure you stress you have a TN, the nominal mast your truck has is not to common. and your right, those welded pins are dowel pins.
i still service fleets of these trucks, but tt's (triple masts) the nominals were always scrap/parts worthy due to their low lifting heights.
