What size screws hold your license plate on and are they metric!?

 

Don't know the screw size to answer your question. I just went to a local hardware and purchased the plastic square tag push-in's. The back side was square so I had to file my round hole to a small square hole so it was a tight fit. While you have your tag off,make a trip to your local slavage yard. Take off the plastic wide raised- groved tread from the running board of a older Ford Explorer. There's two styles so be sure you choose the raised-groved tread. Use a piece of cardboard cut out to get the exact pattern of the flat surrfaced recessed area that surrounds the tag area. Transfer your cardboard pattern to the running board tread's backside then cut with a jig saw. Take a heat gun to the cut out treads backside to put a slight arch into tread to fit flush with your bumper. This is necessary for double sided tape alone isn't strong enough to hold the flat tread surface to our slightly curved area behind your tag. Changes the whole apperance of the cars back. Even looks wider. Squirrel Crusher
