63 Dodge Dart wheel change

I have a 63 Dodge Dart and I was wondering if you guys could steer me in the right direction for upgrading the wheels to 15 in. Or maybe more I'm not sure what fits. Also if I need to change the rear end and the spindles can I just get discs at the same time and like I'm thinking there's probably a Duster or Dart year that would probably plug and play if anybody knows. Thanks a lot
