This body shop sounds like when my brother and one of our friends made a lower quarter panel for a 72 Toyota corona. We found an old water heater laying in a field and they stripped the outer shell off of it for the panel. They shaped it by hand and just bent 90s on the panel for flanges and drilled holes and used #8 machine screws and nuts to hold it all together, then slather it down with bondo. It looked surprisingly good, but was 100% butchery. This was 1985 I think. Good times I tell ya!
