Customs 53 Olds Air Ride

Hi, just bought a 53 Olds 98, I'm wanting to bag it but not having much luck so far finding info on Air Ride for my new acquisition, are there any kits out there? is there anyone on here who's already done this to a 53.
Seems the internet is awash with YouTube tutorials, Forum info and companies selling Air Ride for Chevys & Pontiacs etc.
