Note that the slot where the wheel attaches to the frame is open at one end. Due to th epast corrosion, I would like to order a stainless steel roller assembly with nylon wheel.Also if you notice in the picture, there is a metal piece in that slot which broke off when the wheel was removed. I will likely need to order/replace the component which lost the broken metal attachment that came off with the wheel roller assembly.
