Our favorite fan motor went obsolete, boo hoo... The fan motor we stock has 6 blades and is two speed (just wire it to the connector for the higher speed).  Still fits in the 2 fan shroud system (both original styles). This fan/motor is for the 2 fan set up. Ok so it can be a favorite too! Until I change the photo, you are stuck looking at the obsolete 4 blade fan.
