I am trying to fix the Bobtach on my 843. The one side wallered out from apparently having a broken bushing for what looks like a decade or better, lol. I know RVM says they sell a whole new assembly for $1,350+ shipping. I would like to try and fix this one to get me through until I can afford one of those. Can anyome point me to where I can buy the bushings (6563436) that I can try and weld in. The one hole is extremely wallered out. Has anyone tried building there own bushing to weld in? I don't need perfection since this is a farm use machine, lol. What about a piece of pipe or tubing? Thanks. I'll add a link to a video I just took so you can see how jacked up it is.
