What are they called? What is the white plastic that houses them called? Can I order about 5000 of them because they keep breaking?
The clips are called bird'* beak fasteners, and the housing they clip into is called a doghouse. The doghouse is molded as part of the door panel substrate. Send me a picture, with some dimensions, of the specific clip you have and I will see if I can get some for you. No charge. I have thousands of clips, and may have the ones you need.
