What kind of screws for rear license plate?

[Putzo]

I bought my sonic used, and it only has 2 screws (for the top 2 holes) holding in the license plate. Does anyone know what size screws fit in the license plate hole? I would buy some that match the top ones I am using now, but I know those screws are WAY off, they only work because the plastic piece they screw into is basically all tore up. Thanks for any help.

Take one off while at your local automotive store. You'll get a match

The standard is 1/4" x 3/4". The plastic insert is meant to make it mostly universal. If it fits, it sits.

Just checked my car and the screws my dealer gave me were 1/4" x 5/8" x rusty.

Stop into any dealer and they will have extras they will give you.
