It is really just a minor modification, I thought it was much easier than the old system. I have attached some photos of what I did, here is the description. I used an extra pcb and made a template to attach to the back of box. Make sure that you mount it low enough to accomodate the wireless modules (hard learned lesson on one)! Drill the holes from the back of the box to match the template. I used 10/24 screws that were 1-1/2" long, pass them through the back then secure on the inside with a nut. I then added an extra nut to each bolt to act as the standoff from the back of the box. I used 5/16 tubing cut into sections to create insolators on the top and the bottem of the board to fasten it in the box.
