The position of the panhard in relation to the differential mount is relative to how high the frame is above the ground. You can pull on the panhard or raise or lower the body with a jack to get a slip fit. I'm not sure what you meant by switch???? My '71 had a loud clicking comming from the rear end. You could hear it when I would push the box sideways in back. It turned out to be an elongated hole in the upper frame panhard mount that allowed movement of the panhard. I found a replacement mount but I haven't ground off those rivets yet. Hope this helps. TJ
