I don't know if your clips are really broken. If someone tried to put the molding back on previously, it may be they didn't get the clip fully seated in the molding. The trick is to use a thin smooth bar to hold out the top of the clip from the door. Lift up on the molding, pry out the top of the clip and push the molding onto the clip. There will still be room to remove your bar. I have used a paint can lid remover with most of the hook sanded off. I have had great success many times. You have nothing to lose but you may want to put masking tape above the molding just to make sure you don't scratch the paint. I have done it many times to my 87 GT without scratching the paint. Your other choice is to just remove the door skin and pull out the old clips. Put the skin back on. put the Fiero store clips in the molding and press them in place.
