Product review (5 stars): Quick and easy fix
This worked perfectly and was just the right part to repair my Kenmore dishwasher Model #66513263K112. The wheels had completely broken off of the right side of the upper rack so it wouldn't stay in/on the track. I love that this came with two sets of replacement pieces so that when I had the rack out to install one side, I could do the other at the same time since it was very close to doing the same thing. The biggest downside was that the install photos aren't great in the instruction sheet they include and the adaptor piece for the screw heads was clumsy (I had one that matched  in my drill bit accessories that I used and it and it worked great). Overall though, the price was better than that on the Sears parts site and I got it quite a bit faster because of Prime.
