Mocking up the gas tank in my 27 and I have it placed as far forward as possible to clear the rear end. The issue I'm having is the bottom of the tank is sitting on the floor of the body which is making the tank not sit level. Should I just make spacers (steel plate) to bring the tank up so it sits level and is up off the floor? I will be placing 1/4 inch think rubber between the frame and the tank mounts but that won't be enough to make it sit level.
