Product review (1 stars): does not fit
I ordered two of these kits for my Maytag Atlantis electric dryer model MDE7658AYW.  This product ER303373 ASIN: B006WNLUQM currently has at least two photos on Amazon for the same item. I purchased the one with one oblong ring and one round ring in the photo, but when you look down below or click on "new and used" you may see the photo with two oblong washers and one nylon in the kit. I received the kit with one oblong ring which is actually a wavy metal ring and one yellow nylon ring, one lock ring, a spindle bolt and a nut to secure it from behind the dryer bracket. The bolt that came with this kit is shorter than the bolt it replaced. I installed the bolt, secured it with the nut from behind the dryer bracket, put in the one wavy metal ring first, then the roller, then the yellow nylon ring, then the locking ring and the roller would not spin freely. There is not enough room on this shorter bolt to accommodate the wavy ring and the nylon ring together along with the locking ring AND allow the wheel to rotate freely. So in place of the wavy metal ring, I reinstalled the original stock nylon black ring from the dryer on the new bolt first, then the new roller, then the new yellow nylon ring and the locking ring. This combination allowed the roller to spin freely.
Perhaps if you order from the Amazon page that lists two metal wavy rings you will get a longer bolt to accommodate them, but mine was too short to even use the single included metal wavy obong washer together with the included nylon. Obviously they don't try these out before they sell them.
If you need snap ring pliers I recommend the Irwin ASIN B000JNRR0Y currently 8.72 on Amazon. These come with pins small enough to fit into these dryer snap rings.
