Marker lights, plastic speed nuts/retainers

Does anybody know what the part number is and or where to get the plastic speed nuts, or retainers for the screws that mount in the body for USA car side markers? Need to put my side marker lights back on, but the retainers are brittle and all broke.

You can probably find them at o'reilly auto parts in the pick-a-nut section.  IIRC they are 1/4 inch.

I have a True-Value hardware store that sells a lot of the different plastic mounting and mounting clips, you might try one near you.
