I bought this LIC license plate holder for my 97 GMC Sierra C1500 SLE. Screws on the bottom holes of the metal bumper are perfect. The block itself is solid and well made. I honestly thought it would be a bit flimsy and cheap but was pleasantly surprised. The only thing I didn't like is that they don't have nuts and bolts to attach them to the bumper or bezel on the unit itself. It doesn't matter because I have a lot of these in my garage. Overall good quality for the price.
