Hello everybody.. I've recently bought a Pilot AA (slightly used), and have realized some components are missing. One of them is the brass bushings that get inserted into the arm at the hinge area.. The pins go through them. Are they supposed to be loose in the housing? Regardless, i'd like to buy a small bag of them, because it's one of those things that probably fall out on a regular basis.. Are most people using locktite on this component? Can somebody give me a link? Thanks....
