After doing some more brainstorming, I decided to forgo the Foamular setup and work with just the Coroplast, zipties, spacers, and the steel square tubing.
Framed up and spaced out...
Belly pan installed...
I can install a nose cone in front of the air bag spring to protect it and without worrying about articulation and clearance like the first setup. I still have some more tweaking to do to the belly pan and the side section. I should be able hook up Dark Aero fer a shake down run tomorrow.
