Concours restoration is also archeology. While disassembling the car, Randy noticed what was coated with undercoating, and what wasnt. The gas tank and fuel lines, installed up to the front subframe, had undercoating overspray on them. They were installed early in the cars production, before the undercoating was applied. The brake lines didnt have the overspray on them, nor did the leaf-spring hangers. So, the process originally went something like this: The gas tank and fuel lines were installed first, then everything was undercoated. The rear was left out of the car at this point, probably to ensure that the undercoating is applied completely and evenly. With the rear end out of the car, the ends of the brake lines would be open, possibly plugging them. They also would be hanging loose, allowing them to get bent or kinked. Everything was restored in the aforementioned order. Incidentally, the body plugs in the floorpans also were not painted or undercoated, indicating they may have been installed at the same time as the interior.
