I pulled out the owners manual & started searching for the part. Found that the particular part I needed was not available any more. That was one site. I did some more searching, knowing that most of the dishwashers were made by Whirlpool. When I got on Appliance Pros web site, I found the part. By the way, this slide & adjustment for the rack is metal & not plastic. Once I had the simple tools ready it took but minutes to replace. It is now functioning beautifully. Tools needed for the installation was a flat head screwdriver to remove the old part & a Phillips head to install.
