air bags on 58 merc wagon?

has anyone here done bags on a 58 merc or a 58 anything for that matter. air ride tech told me they dont have a kit specifically for my wagon. the things got leaf springs on the back with a coil spring with the shock inside of it on the front. they said the back would be no problem but i would have to relocate the shocks and make shock mounts for the front. ive got air ride on my bike, that was simple, but i dont know about this setup for the car. theres alot more to it.
