What I did in exactly the same scenario (Except it was Dusters) is I rebuilt the factory AC box with a kit from Detroit Muscle Technologies and installed that under the dash. I'm not quite there yet, but my plan is to install modern components under the hood to work with the original box. These parts are available as a kit from several vendors, but I am trying to piece my own kit together and save a buck. The main thing according to my buddy that is an AC tech and a Journeyman mechanic is to ensure the condenser is sized properly and it should handle that Texas heat no problem. I hopefully am building a future Power Tour car so it will need to handle that southern heat too.
