Have you search for some old fenders? People are selling anything from the 55Chevy's that has a decent panel. We use to just scrap the car when the engine went bad. They were pretty cheap back then. I sold a running 55 Chevy 2 dr. sedan for $100 after I sprayed primer on the entire car. It was a 6 cyl but it was a complete car the year was 1971.
