The vinyl coating on the forward rack of convertible tines dried and cracked away, allowing the steel underneath to rust and deteriorate. It eventually just broke.

After looking the situation over, I decided to remove the entire lower rack and place it on the counter where I could see better. I specified I needed the front tine (part # 24), but received both front and back tines). I used the screwdriver to help slip the old piece out of the plastic clamp end. I broke the end of the first clamp, but fortunately, replacement clamps were also included in the kit. I decided it would be easier to assemble the tines and the clamps first, and then install that into the rack, so I had to remove the other plastic clamp and did so successfully. Then holding the assemblage in place to see just where to snap it into place, I proceeded one clamp at a time and installed it. I kept the new back tine guide just in case someday that one wears out too.
