So I took off the wind deflector on my B200 and now I've gotta fix these two busted plastic bits in the roof lining. I've been checking online and trying to avoid ripping the whole thing out. I've already loosened the lining near the front pillars. The problem is this plastic piece at the front of the rail, it's held in by four screws. I can reach two from the top, but the other two are hidden up there. I'm thinking if I loosen that big plastic piece across the front of the roof, maybe I can get to those hidden screws.
