I have some questions about a pivot bolt on an 8' Western unimount. I replaced it several years ago and I don't remember there being a tube spacer they are calling for. Where does it go? I'm sure the holes in the a-frame and possibly the quadrant are elongated. Can they be repaired? By fabricating new plates? Has anyone had any luck with this? I'm not a welder so I would have to find someone to do it.
