What is the proper procedure for installing the inner chrome grille molding on each side of the 72-74 barracuda grille. Do I place the molding in, then slide the little snug fitting clips over the pins, or do I put the clips in the holes and press the molding into them? Not much success yet. Is there some trick to this or special tool because it is has proved to be a pain so far. Would like to hear from someone who has installed these.
