The glovebox is one big hunk of plastic under that floor. There are four clips that hold the black bit in, but the only holes are for the clips and the hinges.
The glovebox itself is held on with six Torx screws ( four on the bottom, two in the upper corners behind the "kneepads") and three Phillips screws (one big one in the middle of the glovebox behind the door, and two that come through the front of the legshield, behind the "tie"). There's also a rubber band for the glovebox release hinge that usually perishes and needs to be replaced before reinstalling the glovebox.
