help identify this part..please

I have twelve chrome pieces I don't know what car they are too. Came with parts from a different purchase. They are about 4" long. Thank you!!

 

Look like Buick grill teeth. But need better pictures....

 

they look kind of like buick grill teeth would look, but not really...if you try to find a buick that matches them.

Sunlight is not very good for taking pictures of stuff you're trying to identify. Because of the shadows

 

The rear side looks really rough, so rough that im thinking they may be homemade.
