Electric cooling fan

I'm looking for an electric cooling fan with a shroud that will fit in my Dart. I have a 71 Swinger with a slant 6 and stock radiator. I have a fan assembly I think is from a 93 Taurus. The problem I'm having is the fan assembly needs to be slim. I tried a test fit with the Taurus fan and shroud and there isn't enough room between the water pump pulley and the radiator. Anyone have any ideas? Thanks in advance FABO
