FBI's skin is a complete replacement, which requires less filler than an insert. The top extends 1" into the interior bed area, and there is a 1/2" 90 degree bend at the bottom that you can fold over and weld to secure it to your shell. Oh, and it's 18 gauge steel, laser cut and formed on a computer controlled pressbrake.
