Product review (4 stars): Perfect fit; not so perfect instructions.
The dryer kit was just what was needed to stop the piercing noise coming from the dryer.  Everything fit perfectly.  I knew a little about dryers, and also had watched a video on how to repair it. However, I might have had trouble following the instructions given, since they were for a very different model and design.  Otherwise, it was exactly what I needed.  I used the part on a 2007 Whirlpool Duet Dryer, model # WED8300SWO.
