What's with auto body people? . . . .

Body guys are temperamental fume sniffing flakes. Your guys have no manners to boot.

If the car needs a new unibody (no separate frame), do exactly that, find another body. Rust free 72 Scamp/Swinger bodies aren't hard to find. You wouldn't believe what it cost me to get rid of one a couple years ago.

Part of what makes A-bodies so fun is that they are cheap and plentiful. They were cheap cars when new, they made a bajillion of them, and they will never be worth a whole lot. Have fun, but don't spend $10,000 fixing up a $5,000 car.
