I went through the same issue a few weeks ago with the rear side chrome trim piece. The prongs on the two old clips broke off, so I purchased two new plastic clips from gbodyparts.com. I'm sure there are plenty of methods, but I simply drilled two holes where the existing two clip mounting locations were located, then screwed in the two new clips with screws. Fastening the chrome trim piece was tricky. Holding the trim piece at about a 25 degree angle from the body of the car, I was able to insert the clip prongs into the lower part of the trim piece (they are somewhat flexible). I then held the trim piece flush with the body and softly pushed it up a tad until it clipped into place. Hope that helps.
