January's issue of The GoodGuys Street Rod [censored]. had a small story about fuel tanks in pickups. I don't remeber who was selling them, but they used a cabnet grade hinge sytem and mounted it under one of the boards. With some sort of electronic release the whole board would hinge open and fuel cap was easy to get to. When it was shut, you couldn't tell from the picture where it was. They cut the board right at the steel strip line on both sides. Joe
