Not sure what they are called but I guess I need those plastic parts that go into the rear license bracket where I can screw the screws. I just have the plain metal bracket and so far the license plate is held by zip ties. Any body knows what they are and where to get them?

 

Any auto supply store would have them.

 

are you talking about license plate nuts like the ones below? you can get these at any parts store or on Amazon

 

Yes, those are the exact things I need. Thank you guys.
