I used all this stuff to relocate the battery to the rear. I even cut the stock battery tray out for a simpler look under the hood. I've had this idea to take a sumbergable type battery box and mount it in the rear then tig weld it into place. This will give a lower point of weight distribution in the rear cargo area and also free up space there as well. But I have a long way to go till I get to that area of the car. We'll see though.
