Tim and I had measurements of the bushings and holes. I may have had the measurements on the links too but cannot think of where they might be now. If someone does not answer soon, I may try and measure mine without taking them apart. These are the bushings we decided worked but they are too thick and need to be turned down to barely clear the links. http://www.mcmaster.com/#catalog/118/1126/=kx8syk part number 6338K457
