That might hold, however when the guy who painted my car suggested using some type of adhesive that he swore would hold it ( I don't know what type so I would not wish to generalize), I agreed, but I was travelling down a county road doing around 100 (yes I was exceeding the posted speed limit) and the drivers side scoop blew off. right before a show that I attended. so after that I reattached them with 4 allen head bolts you can position them with the allen wrench and they are low profile. I did have to drill the sheet metal so You want to be sure you like them. I also used the adhesive again, in addition if you do not plan to make the scoops functional I suggest not completely sealing up the seams as they catch a lot more air than you might think. Shelby used pop rivets on the original shelby mustangs I believe.
