383 Radiator and Fan

Getting ready to install my rebuilt engine and I am having a hard time with the cooling system. My original radiator has a big crack in it and I am missing the fan and shroud. I thought I could just simply get an aftermarket radiator and buy the fan/shroud. Its like I opened up Pamdora's box. Apparently it was a one year fan design and the aftermarket radiators in the $300 range will not work with the old fan shrouds. I thought I could just simply by an after market fan but that too seems more complex than I thought. I was told not to go with the electric fans that you can get for the aftermarket radiators. Has anyone been down this road who can offer some insight?I attached some pictures that I found of the original fan for reference.
