I bought a fuel cell to put between the frame rails of my sons 67. I didn't like the idea of the fuel neck sticking out in case of a roll over. I was thinking more of my sons safety than where he was going to carry his spare. I couldn't think of any other way to eliminate that hazard without relocating the tank. I never got it installed and he had to sell his truck. Here is the setup I have.
