Test fitting the firewall
The firewall is a continuous, fully welded sheet of steel between the engine compartment and the cockpit. SCCA formula 1000 rules allow it to be a stressed panel, thus the continouous welding. Around the fuel tank it will be a double wall of steel for extra protection against engine explosions, insulated with shredded fiberglass to keep the fuel cool.
