no no no... i was kidding. the clip go under the sunroof channel. then you lay the deflector on top of them. then you screw the screw into the clips. as you tighten the screws it snuggs it down to the roof. no holes at all.
the bolt was just a joke. 2 clips like the picture above. on a scale of 1-10 hardness to install i give it a 1.
the window deflectors are held in place with 3M tape you can get at auto zone.
