I made that part, on my JD 4000 / 4020 tractors, there is not enough space to use a double EYE cylinder, one can get bushing stock from a machine shop, I was out of the sizes I wanted, so I took some shaft and drilled to the size I wanted, 1" and then welded them together to make the part, ( I would guess John Deere would sell the part, as it its part of the top link on old 20 series tractors,
