Proper Radiator

Guys, I know that my newly acquired '69 Dodge Dart Swinger 340 4-speed has the wrong radiator and fan shroud, maybe the fan too. The engine is I believe a '70 340, it has a six pack on it but I do not believe it is a TA/AAR engine. Radiator is a 3 row. Bottom tank has no drain and I would like to straighten things out. I am confused about lower hose exit Rt. or Lt. side. The water pump inlet is on the Rt. or passenger side so whats with the parts suppliers saying it should be on the drivers side? The current radiator works fine but I want to correct it.
