Stainless Steel Firewall Covers....
We sprayed Bedliner, then I installed the original firewall insulation, then an additional layer of foil-backed fibrous insulation.
Finally, installed the stainless Steel Bulkhead Panels. "Nut-Serts" were set into the original firewall. The machine screws on the corners press the steel against the insulation to avoid any potential for vibration.
Nutserts in the steel also hold the tank cover on. More nutserts and P-clamps will be used to secure the engine bay wiring harness (which is just now reaching completion).
I'll get a picture soon with the tank cover on.
