Bought but never used. I have a license plate bushing that acts like a rubber bumper. I wanted to put this rubber bumper on the license plate mounting kit on my car's front bumper but couldn't line up all the screw holes. Also, I didn't want to drill unnecessary holes in the front bumper. To complicate matters further, I wanted to use anti-theft screws that only come in a certain length. This assembly set makes a solid impression and is made of high-quality material. It might work in most situations, but not for me.
