I'm the same, I like originality, or at least to know how it was, then decide. I think these work better on some models and some colours than others.
Mine had them originally as optioned, but seems to have been a dealer rivet-on set. It has been mentioned in the past by original owners or dealer workers that some options were left incomplete on arrival and is how some vehicles came to have the rivet-on type. I'd have thought they could just as easily have supplied the GM adhesive roll. Who knows, easier to apply, short supply, no idea. I haven't seen any reference to this occurring. There's also the chance that my car originally had adhesive but at a later date, for whatever reason, had rivet-on set installed. Possible also. Except that there's also original owners with optioned moulds and they are riveted type, and not factory type.
All I know is that the only mark on my car is a small crease in the door right on the angle below the door lock, courtesy of an auto electrician. He denied knowing anything about it, looks exactly like if you let go of a floor jack handle.......doonk. Body mould would have protected it and not even been marked. So from now on, I put body moulds on all trolley floor jack handles....
