I'll let the show speak for itself, but the biggest items that we touched on were the specifics of the LS Engine placement, the new firewall, the completion of the roll cage, the installation of rear shoulder-seat-belts that come up through through the package tray, and the child seat safety hooks (no joke - this was something I asked him for so I'd have the option to haul my kids around in their car seats for the next few years)!
