What size fan for A body?

What size fan for a '72 Duster. I believe I took off a 17" for the Slant six that was inthe car originally. Is it still a 17" fan blade for the 360 cu. in I put in t replace the SL6?

Thanks,

I think they are still about 17-18 inches but have more blades.
The sixes had four blades for the most part I think, and the V8's had 5 and seven blades.
I have a perfectly good direct drive seven if you need it, and you can have it for the shipping if you want it.
