Plastic Square Door Clips

[iloveguns22]

Does anyone know where I can get those square plastic clips that go into the metal of the door that the screws on the bottom of the door panel screw into?

I used to see them in the HELP! section at the autoparts stores...Not sure if they are still available or not.

Autozone and Oreillys both have them in the fastener sections.
