have a drivers side lock clyinder that needs to come out and get serviced, feels like a broken off key or internal hanging up, sooo i pulled panel off to get a feel for the removal and one of the door panel clips, large square plastic catches that drop into door, fell out after i pulled panel away...... can they be purchased ??if it wasnt right at the door handle i wouldnt be concerned as much but SOME people really pull on door handles...
