Spring Relocation without mini tub...

Boy! This is great reading.I want to keep my stock fuel cell. All I've heard was that I have to run a fuel cell when mini tubbing my duster, in order to run my exhaust. By any chance, doe anyone out there have pictures of mini tubbing with stock fuel cell? any help is much appreciated. BTW, I want to run 15 x 10 wheels with 6.5 backspacing. thanks!
