No problem. Some very good advice, leaving it could be an option but we all know what it is like to have something gnaw at you when your trying to fall asleep at night. The first time it might be a little more time consuming but after just a little practice it gets really quick. The hinges move effortlessly and you sleep better at night knowing you have a nice mechanical hinge. I put them on all my planes now and if one of my CA hinges looks iffy I replace it. Good luck and let us know how it turns out.
