This is what I did to mount the Strobe power. Since I wanted to hide the Z bracket under the box it made it hard to match drill the holes to the bottom of the skin. I used some double sided tape (Used for mounting Golf club hand grips, stuck a strip under the bracket while it was clamped to the box. I then stuck the whole unit where I wanted it in the floor. I then picked up just the box off the bracket leaving the Z bracket in place.
