Really well put together guide. You make it easy for the person with no wiring knowledge to put this together. One problem I ran into with this is that for the 3x5" plates you have listed, the floor mounting flange is way to big to fit 3" plates. I'm going to be finding a 2 3/4" piece of aluminum pipe and welding it to the top, unless someone has a better idea/or easier. Thanks for the time you took to put this together for us!
