If my memory serves, the keyhole in the plastic clip is left to right. Its been a lot of years so I don't recall exactly. I removed the 2 screws and shoved the molding forward and back, moving some clips one way or the other to release them from the welded stud.
I pried the molding off some of the clips from the bottom, and broke a few clips too. After a few clips were conquered, The molding would bow outward a little without damage. I did successfully transplant those molding to a car that didn't have, using screws in the remaining unbroken clips.
