I need help with identifying two small clips that I found under my smart in the garage. They are metal, 1 3/16" long, 1/4" wide, 5/32" high. There is a point on each end directed inwards. There is a slot down the center with curved edges as if to grip something. On the edges of the slot are remains of Blue paint,my smart is Blue. One was found last winter/spring, the second was found a week ago. Nothing appears to be lose and after looking under the car I have not found a thing where these clips would go. Any ideas would be appreciated.
