Hey, I was browsing around the web and came across this little gem:

ClipsAndFasteners.com - Automotive Retainers,Clips and Fasteners

They have pretty much ANYTHING you could look for when it comes to those little non-descript clips you can't seem to find a name for. And I mean ANYTHING. Not sure where else to stick this, it seems 4th gen general is the most active area on here. Feel free to move wherever is necessary!
