I stripped my trim off this summer (MK1A) and don’t remember any nuts, bolts, or screws. I slipped a wide blade putty knife behind the chrome and gave it a little "pry". DISCLAIMER: I was not concerned with damaging the paint. My car has what I think are the original mounting hardware. They look like raised head pop rivets and I have reinstalled (snap-on) and re-removed the trim again since the initial removal with no trouble. I also have a couple spare Tiger doors(MK1) that have plastic trim retainers which are about 1/2 " long but they didn’t come with the chrome trim so I don’t know how well they work. Bob
