In PA here, so I don't need front plates, but there are marks on my front bumper where holes would be drilled for one.
The rear has two tabs on the inner edge with two "posts" located where the right screws would go. The plate only screws to the bracket on the left (outer) side.
I also had six screws in a small bag in the glove box. Four would be for the front, two for the rear.
Hope this helps.
