Finished most of the front firewall, intrusion panels, and interior panels. Rather than using rivets and drilling into the chassis tubes, I ended up welding on a bunch of tabs and using 1/4 and 10-32 rivnuts.
For the intrusion panels, I used 6061-T6 1/8″. The interior panels were actually the FFR exteriors, but I trimmed them for the interior. All the panels are then fastened using 1″ counter sunk spacers.
Also cut away the door mounts.
