Swampcat...Rust problem is the windshield channel area on top and continues into inside cab. Roof looks fine, but that inner panel is not good. Yeah, having gpas truck means alot. As far as a donor vehicle...I spotted a 57 behind a metal building the other day on the way to the gym. Too far away to get real close look at it, but it has a 57 grill for sure. Looks complete, but not restored by any means. Gonna call the guy today about it...who knows, he might be looking to get rid of it for a few hundred dollars, or he might want 6,000 for it. Never hurts to ask I guess.
