68 Barracuda A/C

I'm thinking of installing A/C in my non-A/C 68 Barracuda. I was also considering installing a factory A/C box while I have the interior out. Then I noticed you get into the different dash bezel and controls, etc. Will any other A-body boxes fit the Barracuda? I already have a compressor from a Magnum swap. Biggest thing is whether the Valiant or Dart boxes will work. Seems to be a lot more of them around. Thanks
