Need a 3673916 Radiator

Hey all,
I am still searching for a 1973 A Body 26" Radiator for a factory 4spd. I have been searching for several years. All I really need is the top tank that has the part number. I need this as I am restoring a very rare Dodge Dart Sport 340 4spd car with the factory hood scoop, no vinyl top, JF1 Pale Green car. If you have this radiator or know of one please contact me. Thanks.
