I had a heck of hard time finding these, seems all the suppliers sell the repop chrome with the clips, but nobody sells just the clips, or knew where to get em
Except:
http://www.elcaminostore.com/onlinestore/product08-3692.htm

Elcamino store has them... Then are the same as the 68-72 Chevelle & Elcamino door chrome clips (front and back of each door chrome pecie, and also the same as 70-72 elcamino upper and lower tailgate chrome clips (L&R side of each chrome peice).

Just thought i'd post this with the link to help anyone else out who had trouble finding a source for these...

Thanks Ben. They also look like the clips that hold the horizontal aluminum trim across the back of my '67 Malibu.
