STOP! Don't trim any of the clips. Fit the fatter circular part of the clip into the body hole. Then tap in the center pin to secure it.When installing the trim you will need to angle it slightly them smack it firmly in place clip section by section. Hard to explain but when you start it will become clear. If the clips aren't going in the hole it could be that the hole has too much paint in it. You can carefully ream out some of the paint without chipping the paint. Good luck!
