I've got a '66 hood that is in excellent condition. If I removed the fiberglass cowl hood, I could put the steel hood on and drive away. A previous owner must have painted it at the same time as the rest of the car and the cowl hood. Of course, the color wouldn't be right, but the point I'm making is that it wouldn't require any body work prior to repaint.
OOPS --- just after posting the previous message, I see your title line specified an SS hood. I guess I must have focused only on the "looking for a good clean 66-67 hood" in the body of the message.
I have a repo hood that's was painted on car a week or so sitting in garage. If your at car craft see the 72 orange car ask for his brother if you want to talk.
