Lil black push in retainers (fender liner)

the black fender liner is held in place by these lil black push in retainers, can i just get replacment retainers from any old automotive store, or do i got get special one? cant acctually remember seeing them at the shop i goto but i dont ever recall acctually looking for them either.

Are they the ones with the pin in the center?

Eitherway, if you need to replace them, some are available in stores, however i had no choice once to go to the dealer and surprisingly they were really cheap.

Yep...autozone, napa, pepboys, and last resort...the dealer...

If you find a place that has a "help" (yes that is the brand name) section. They always have weird clips and things. I actually have some in my tool box of the ones you need. But i need to keep em.
