Product review (5 stars): Works fine for my Kitchenaid
It fits my Kitchenaid dishwasher, and is the second replacement kit we've had to use.  The original plastic pieces broke, as did the replacement plastic pieces.  I'm hopeful these aluminum pieces will stand the test of time.
The installation instructions have faded pictures, making them tough to decipher, but it's not difficult, and there are plenty of videos on the web to show you the procedure.  It took me about 15 minutes, but I have a little practice.
Some of the screws are a weird head, but the kit comes with a nifty widget that allows you to use a #2 phillips (very common).
