The problem most have with air ride, aside from aesthetics, is that by the time you have cut the car to pieces and welded in all of your fabricated mountings... the car is pretty much destroyed. It would be a ridiculous amount of work to install and worse to ever consider trying to undo. Body on frame construction makes the install easier and cheaper... but still destroys the frame and what ever sheet metal that gets cut. Unibody cars like ours are stronger than body on frame, but rely on every piece of metal that was welded or bolted to make up that strength. Simply welding in a metal brace doesnt bring that back when its in a new position with less leverage to hold that part of the body in position.
Remember, once the cutting begins the car is pretty much valueless and hard to sell. Between the expense and amount of skilled labor and expensive equipment involved to jig it up and weld in the mounting locations correctly... very few ever seem to get finished, or finished well. The engineering of a suspension is far more complicated than just bolting in that part and the aftermarket suppliers you would get parts from only need worry about fit... you're the engineer. This makes all ride quality and handling concerns your problem, and the car will likely be considered unsafe for road use if you ever get an inspection or piss off a cop. So put aside some funds for the enclosed trailer you will need to go anywhere.
You will get lots of help here if your looking to repair or preserve. We wont discourage modifications for improvement unless the car is exceptionally rare or original... but those mechanical upgrades, like a new carb, can be undone as easily as they were done and make the car easier to enjoy. Most of us wont like to see a car chopped up to do a modification that most of us know wont turn out well. Its not that we are old and hateful, we are experienced and knowledgable. I am a Master Tech and have an extensive resume in my field, some of these guys have engineering backgrounds, others have many decades of racing and loving and restoring thier cars. Most of the time if we say its a bad idea, its not simple hate... we have reasons.
BTW
Welcome... you have a very nice looking car.
