Early A fan Shroud

Don't know if it was an option or what. They're made of sheet metal. I've seen pictures of a couple of members cars that had them. Maybe they only came with AC? I have a factory '64 V8 car. It came with a 6 cylinder sized radiator & no shroud. My mom had a '65 6 cylinder Barracuda. No shroud on it either. I'm going to have to modify the core support opening on my car to make the V8 radiator fit.
