1965 Formula S w/AC: What is Factory Correct Fan?

Its crazy how many fans were used, surprised to see so many in the parts book. Your 7 blade fan is a bit different than the one I have pictured. I did a bit more research on the car I got the 7 blade fan from (pictured in post #3). It was about 15 years ago, but I took some pictures of the car and the fender tag, which I just looked at, and it indicates E-1 on the plate, which translates to A/C with heater. Believe it to be a California car, locally owned at that time. The AC was all removed and given to me, he changed the engine and put a 5 speed Tremec in it. The dash still had the AC buttons. These are 55 year old cars though, things do get changed out.
