Wheel Well Liner Retaining Clips - Source

Here are a couple pics of the OEM next to the autobodyclips version. Look exactly the same except as mentioned the centers cant be pushed in for extraction.

Someone please correct me if I'm wrong, but neither of those clip are OEM.

I think your previous owner already replaced all your OEM clips with aftermarket ones.

The oem clip you push in the center slightly to remove the clip. The ones you are showing, you have to pull out the center to remove the clip.

Sorry, after looking at a couple of my OEM clip the picture could have been when you pull out the center to reinsert the clips.

The differences I have found with OEM clips and aftermarket clips is how the center of the clip operates. On the OEM clips, you push the center in slighty (don't push it to far, you will break the $6 clip). The aftermarket clips, you have to pull the center out.
