Fan too close to radiator?

Syleng1 said
On my 66’ 273 with factory radiator and water pump, I’m running an early 2000 style Dakota fan and clutch. Fits diameter wise for the factory radiator and the factory metal shroud. You need a shroud. 22” radiator needs all it can get to pull air thru that small opening. The clutch fan is quiet and works well.

?? A 2000ish Dakota has a Magnum engine= reverse rotation fan and shaft mount clutch ... How did you accomplish this? Not being nit-picky, just curious.
