When I bought my 300U years ago someone had taken it apart and never replaced the dowel pin.I've never been able to keep the steering case tight because of that. I took it apart and put everything back together the way it should be. Now I need the dowel. Messicks site says to call.I don't know if that means not available. I&T manual says to ream the hole first so I don't understand how a pre-made dowel would fit anyway. Has anyone replaced the dowel and how did you do it or find it. I'm thinking I will have to have one made. Mine is a bit larger than 5/8 so I'm thinking I can't buy one off the shelf.Need some advise on this one.
