Idk if you even can anymore. With mobile hvac the cars themselves are designed to be obsolete in 5 or 10 years. So the older stuff is now really obsolete, like v belt compressor clutch pulleys instead of serpentine belt, etc
With residential and the switch to r410A, we cleared all those out back in 2009 at the place I worked so idk how you'd find a NIB air conditioner and coil unless someone had sat on one
