If your just wanting toget rid of it ,why can't you unbolt it ,then have it winched out of the hole,now fill the hole with some dirt.
do no longer restoration the air suspension convert it over to known coil springs. the fee and problems with the air isn't worth it you restoration the subject now and quickly some thing else with the air device will fail and it is going on and on .
Cut out the air suspension and put in coil springs to eliminate any and all problems related to the air suspension system. Good luck.
are you planning to reinstall it at another location? if so, that's really cool. good luck. drink lots of water
