Found the correct racks on Appliance Parts.com. They shipped as promised. When I received them, however, I couldn't figure out how to replace the top rack. Didn't know how to get the end cap off Sooo - I went back on the website and watched the repair video and voila - was easy. All that was required was a flathead screwdriver and the knowledge of where to use it!!!
Replacements in the dishwasher in 5 minutes or less. Great website and very helpful videos. I will recommend this website to others.
