If you ever lose a clip, you might check for used clips from a body shop. They usually have drawers packed with them and they might let you pick out some for a few bucks - but it's kind of a scavenger hunt. In Miami, I bought some from
a shop that does windshield replacement. Instead of using 2-sided tape, the glue I used to attach it to the trim was GE Iron grip adhesive. Mopar Parts Source and Chrysler Parts Inc also have Crossfire clips for windshield molding you can buy online.
