So here's how I did the front frame reinforcement. The bumper brackets fit through the square section in the front, which is a bit oversized in order to fit my rotisserie. I plan on gusseting that part up a bit for stiffness once the rotisserie work is done. The upper firewall area is reinforced with 1/8" steel. The point is that getting rid of the battery tray area made this a heck of a lot less complicated on the passenger's side than it would have been.
