The part I ordered arrived. I removed the upper rack and set it on kittchen table to repair. I have average mechanical ability. I compared the good side to the broken side. Identifying the separate parts i figured out how thew attached, all parts are snapped into place. Thankfully the connections are exposed and can be pushed or squeezed to release. I used my hands, small straight blade screw driver and and needle nose pliers for the job. took about 30 minutes to do.
