I'm trying to find details on the upper firewall and gas tank on my roadster. I know the interior of the car is a finished gas tank but there is about an inch gap between the firewall and the front of the tank. If the top of the tank is indeed the exterior of the cowl where does it separate from the firewall and how are these pieces attached. i have been told the exterior body on top of the cowl is a cover over the gas tank but that doesnt seem correct to my way of thinking. Anyone have pictures of the pieces and how they are attached?
