The clip you have at the rear of the trim is not correct. There should be a square hole in the metal to receive a plastic spacer that the screw goes into. The original clips were metal with one spring. The plastic clips are definitely not original, but they are probably the best to use. The metal clips are almost impossible to use, without denting the trim from the inside out, unless the originals fit better than the reproductions. I used the Auveco plastic clips on mine. I had to sand them down a little thinner, because they were too thick, but they worked well.
