I used a 1969 Mustang gas tank. Remove the rivets from the rear crossmember, and remove it to allow the gas tank to slide between the rails. I had to trim about a 1/4" off of the bottom "C" channel of the frame, but it worked out awesome. Ultimately I ended up welding a frame out of angle for the tank to screw to. The Mustang tank top originally is used as the trunk floor. It screws down around the perimeter of the tank with metal screws through the tank flanges.
