Fred, What circumstance has you replacing a front rail pin with a smaller "shank" or core diameter than the original? Usually it is the other way around, requiring the technician to enlarge the hole slightly for replacement pins. Are you trying to put in the new M&H anodized pins? If that's the case, I spoke with Bruce Clark at the Mid-Atlantic Conference and he stated that they would be providing nylon bushings to tap into the keyframe and then the technician would tap the pins into an undersize hole in the nylon for a press fit.
