I'm looking for some body panel clips like these. The way they work is you insert them with the center part out, push the center part so it is flush with the head to lock it in place, and push it in further than the head to release them. They're kind of like the stock retainer pin clip things that hold in the wheel well liners, but they're easier to get out. I found them on a website, but there is a minimum $100 order. It is manufactured by TWFastex, part number 1R56 A 9 061 02. I did a search on Google, but came up empty handed. Anyone know where I can get some? Here's a quote from the information on the site where I found them and a picture.
The removable rivet is a one-piece unit that is quickly installed by hand or with automatic equipment. It is ideally
suited for applications where access to the back of the panel is impossible. The rivet is removable and re-usable
by using the tip of a thin, blunt-pointed instrument to depress the center of the rivet and release the locking mechanism.
Removable rivets are manufactured in a black polyacetal material.
