It could not have been simpler. I typed in the dryer model number, and found a short video that explained how to take the old switch off ad replace it. I took off the old switch, photographed how it was wired so I could correctly rewire the new one, then typed in THAT model number. Two days later, I had the new switch. I got it rewired--did have to have a little assistance from a family member to get it slotted in correctly, but I spent 30-some dollars on a new switch rather than 400-some on a new dryer! I used Appliance PartsPros.com to order parts for an even older range/oven. You can get the parts you need AND clear concise instructions on what to do with them when you get them. Based on these two experiences, I would rate AppPartsPros a 50 on a scale of 1-10.
