Install aftermarket A/C in a 73 Dart Sport

Hi all,

I'm looking to install an A/C kit into my no-A/C Dart Sport. However I can't seem to find suitable kits. I have found this 1972 kit: https://www.classicautoair.com/shop...tems/1972-dodge-dart-air-conditioning-system/

Does anyone know if this will fit my 1973 model?
And should i look for the Dart or the Demon setup?

Thanks for thinking along!
