I started on my mustang gas tank install, here's a couple pics. I went with the bigger '70 tank, 22 gallon I believe.
I took out the existing X member here: [image][/image]
..and flipped it over and welded it in the back. Now I have a built in mounting surface for the rear of the tank and I'll use some 1.5 or 2" L channel for the front. [image][/image]
