This move nearly killed me!! :-)  To think about taking a drill bit to the car....the hole was made then squared off with a square file (the fuba base is square to keep it from moving around...there is a gap between the inner and outer fibreglass...I squeezed in fibreglass body filler to take up the gap to prevent any cracking and relieve stress when tightening up the retaining nut.
