I am currently fabbing one very similar to wolfmans with some slight changes.
Debating on keeping access to fx4 tow hook since I will already have access to my tow hitch, my lights in the bumper will be aftermarket lights (not a fan of factory fogs) and my top is square tube.
The only part I cardboarded was the top plate that bumps down at an angle and the wrap arounds to the sides. Everything else you can take measurements and trim if need be.
Plasma cutter helped a lot
I would recommend 1/8" if you are fabbing similar to woffmans, I dont have my mounting reinforcements in yet and im at 67lbs
I did you a really hard steel so it's really dense.
