I am needing to find roller parts for the upper tray on my KD-18 KitchenAid Imperial dishwasher. I would love to find replacement racks both upper and lower, but thought I would try first to find the roller parts that connect on the upper rack. Can anyone offer suggestions on where to find? My machine works well, but the upper rack now no longer works without either a full replacement or new roller parts on the rack.
