Put two short screws into the holes on the spoiler.. put tipex or similar onto the heads of the screws line the spoiler up on the tailgate.. it will leave tip ex marks where you need to drill..
That or just tiger seal it on and hold with tape until it dries.. don't use to much tho as it will come out the sides and onto the glass.
