hello all, this is my first post having just joined. I would appreciate any advice on the subject of replacing a faulty nut. I have a 2007 412 CE and need to replace the damaged nut. I have ordered a Graph tech replacement which I understand is a standard Taylor fit. How easy is it to get the old one out without damage and will it need any sanding when putting the new one in. Or should I just leave it to a professional !!. I am keen to have a go myself. Thanks . Ian.
