Retro fitting an AC setup.

Has anyone attempted, succeeded, or have information on retro fitting a 67-72 factory AC setup into an earlier a-body? Want to install a factory AC unit in my wife's 1965 Dart GT and I'm trying to stay away from a Knee Knocker setup. 20160316_183752.jpg 22556238_1722078791144650_1216035858_o.jpg
