The mounting is the only negative to the spoiler. They provide about 10 small 1032 screws, nuts and washers
I have never gone to that much trouble and I don’t think using them to mount is very secure.
I have always used sheet metal screws to attach the lip to the valance.
The last spoiler I purchased from them was trimmed very differently than my previous examples, and the mounting lip was nearly nonexistent.
if you study the pictures you can see my old spoiler has a half inch lip compared to the new spoiler with barely 1/4 inch lip. I went to the trouble of adding mounting tabs but I’ve never had to do this previously. Whoever trimmed that spoiler when it came out of the mold took off too much material. ☹️☹️😡
