I wish I'd read this post a day earlier. I did the same thing today. Managed to forceably remove the old clips. Carefully lined up the new clips and fit the moulding to the door, making sure it was attached securely. Then when I stepped back from my handy work I saw that the trim was supposed to go over the edging first. Too late unfortunately as it was solidly attached. Now it sticks out half a cm at the back, very annoying.
