Without taking the whole thing apart right now, here's a quick pic of where the Panavise bracket goes in behind the glove box door. Its held on by two bolts, one of which is visible in the pic here, and the other is behind the glove box trim edge. They are OEM bolts that are already there. Simply take stuff apart and add in the bracket and put back together.
Out of the four Panavise brackets I have done, this seems to be one of the sturdier mounting solutions. I would not be afraid to put a 10" tablet or likewise sized laptop on it utilizing a proper shock-absorbing type arm to hold the computer. I would be hesitant to do the same on either of the LX470 Panavise brackets I have cause those ones just screw into the plastic of the dash (out of site behind the trim and in really nice spots, however). The Tacoma (first Gen) one I installed utilized the radio head unit bolts and it was also a really solid bracket
