good info here
If you go to the forums sections here then to oday forums then photo/project forums you find a couple of photos of the same project. Below is the site for one. I bought all the gear to do mine the same over a year ago. I marked the holes, drilled them filled them with epoxy so as to have a good medium to redrill and place the hardware but haven't gotten around to it yet! Mine will be set up like it is in this photo.Good luck,Mike
