Note: I am only talking about the bottom door trim, not the grate foot pads. It was easy, open the oven door part way, lift off the door, turn the door upside down, remove 8 screws, replace the trim and reverse the process. While the trim was off, we removed the opaque glass front and cleaned the inside. It had collected some dirt and stains. Along with new drip pans, the stove looks as good as new.
Originally I ordered the wrong part, I'm not sure how. I reordered the correct part and returned the wrong part with no problem. The picture of the trim is small and I did not remove the door before I ordered the first time. If I had removed the door I would have seen that it was different than the picture.
