I know people are going to call me crazy but...Its possible to get back to air ride?

[love dodge]

I finally got an h2..the color i wanted,the options i wanted,not too bad mileage and a good price..But the previous owner wasn't a car guy so the first time he got himself into air ride suspension problems the guy at the dealer talked him out to switch to regular springs...(bastard).
So now i got his truck but with the springs conversion but i want the air ride..is this possible?
I know the service was done at the dealer and he was robbed at 1600 grand for the service but now i dont have the feature for inflating the stuff...I dont even know if the compressor still there...
