where do I find the clips for headlight bezels

I have a 1970 Skylark, but I'm having a terrible time finding the clips that clip into the radiator core support, and allow you to screw the headlight bezels to the car.... any ideas?

Thank you

ps - I've check OPGI, Year One (might be there, but couldn't find it), ebay, google, bing, auto body supplier....

 

oldbuickparts.com used to carry them, but I can't find them on the web site.

 

I got mine from them too.
They are right here: http://www.oldbuickparts.com/catalog/headlamp-bezel-nut-1969-72-buick-p-20967.html

 

you guys are awesome, thanks - I was just there and couldn't find it, then hit your link and voila.

thanks again.

 

Are these the adjustment screws?
If so I found them at autozone and Napa on the shelf in the help section
