This is the tube/sleeve that goes inside the box on the Pivot Rib on Meyer C Series plows. The Pivot Box MUST be cut open, and the old sleeve cut out. It is welded on the front side so it is not an easy task. The picture shows the box cut open to expose the Pivot Tube/Sleeve. For some it might be easier to just replacethe whole Pivot Rib assembly. Sold EACH.
