Plastic retainer clips for trim kits, v shaped

Anyone know where I can get some of the plastic retainer clips that come with the scosche radio kits? I am missing a couple and cant find them anywhere.

 

I used the ones from the dealer on my metra kit (they worked better than the ones they included).

 

I used the ones that came off the existing radio. I unfortunately broke one takin the stereo apart, but picked up 5 of that at my dealer this morning. They were only $1.50 a piece.
