Exactly what Oldmanmopar said.When installing them you don't just push them on. Stick the single end in place insert a flat screw driver in the double end and pry back while pushing them in place. I always would squeeze them and make them tighter before install so they hold the box halves tight. They always seem to loosen up when removing them. You can hold the screw driver sideways at locations where you can't go dead on.
