They should like up with the bumper bolts just in front of the wheel well. The bolts enclosed should be self tapping. Some will line up with existing bolts and others will have to be tapped in. I just checked my car to verify. Thinking back, I do remember tapping some in. Sorry for the misdirection. Just make sure everything is lined up. Once you get them in, they are pretty solid. Watch out for parking curbs. Some are high enough that they will hit and destroy your work. Hope that helps!
