Correct. There are those little covers they just pop off and reveal the screws. They are a pain to get back on. Or I should say to stay on. It will give you more access either way.Good tip @Kbratko, I will check for that first. When you say you removed the molding, I assume you meant from inside? How did you do that? There are what appear to be a couple of small screw covers in the vinyl ring in the ceiling around the windows, is that actually what they are? Do they pry off to reveal screws, or is there something else involved?
