Welcome and congrats. I have a 66 fish too with factory AC, but I wondering about the PCV hose running to the air cleaner. Mine doesn't have that. Could that be something that came on a California emissions package or added aftermarket?

Actually the valve cover breather was going to the air cleaner and it looked like it was something someone added at home, it didn't look factory.
