Someone could make them for you if you know what it looks like. I had a friend in VA that had some old CJ8s we took apart and I know he made sure we salvaged those. Let me see if I can find his contact info...
Edit: His screen name is CBROGERS but he's not on the forum much at all (4 posts). He's in the same club as BESRK. Since Carl builds CJ8s, he may not want to give them up but maybe Eddie can get them and fabricate copies.
Vibration? Bump steer? Wandering? Read: Steering, suspension, and driveline basics. An article on how it works and where to look for problems.
