fan blade......a/c truck question??

[FIREBALL]

ok guys did a a/c 71-72 pickup with a 350 have a 6 or 7 blade radiator fan blade, what was the size 17" or 18" or? Reason i ask its i got a flex a lite fan and i'd rather go back to a clutch style one. I'm in the market for one as well as who makes a good clutch i need one of those too. I need answers as soon as possible so i can get it back up and rolling down the road properly. So if some one has a blade for sale shoot me a couple pics and price and also where to get/buy a good clutch for it too. Thanks guys ............
