On the Campy downtube braze-on shifters, the little bolt that screws into the braze-on on the right hand side, won't screw in all the way. It is about 4mms shy I reckon of where it should be. I've tried CRC in the hole, and scratching down the hole with a paper clip and safety pin (to try and clear the thread), but I can't seem to get it to go any further. Any ideas?
