what clutchfan 65 dart 273ci with air ?

Here is the OE 2536 675 clutch unit next to the Hayden 2947 that mopardude318 suggested... I had to use the 2947 Hayden when I installed the thicker Aluminum Radiator...
All I can say is the New Hayden 2947 has worked Very Well !!!
Oh, Let me add, Yes Dana67Dart you would have lost the bet !!! :)
