I need to install the front license plate bracket which means drilling into the bumper. Not a huge deal for me so I don't really care for aftermarket no drill offerings. I don't have a rivet gun and would like to be able to take the bracket off once in a while to clean everything behind it. Has anyone used nuts and bolts instead? It seems hard to reach behind the bumper to tighten things down this way. Anyone have other ideas how I can secure the front bracket while still be able to easily take it off?
