I had to remove two screws with some kind of funky head. I was amazed to find I had the proper tool. I only wish I had replaced these screws with ones that have a phillips head, but I didn't. I did have to remove two more small screws on the inside panel. No problem there. The parts that were sent fit very nicely and I don't have to buy my wife a new oven, yet. It is 17 years old so that day is coming. By the way, these parts cost less than 1/2 of what GE wanted. Also, the GE site was near impossible to navigate while AppliancePartsPros.com was very easy to find these 17 year old parts. They were in stock and were sent out quickly. Very impressive!
