Air Bags/handicapped access on a 4x4?

[trukman1]

I have a 67 1-ton with a 6-inch overall leaf spring lift. I am getting ready to have the truck redone and wondered if anyone can steer me in the direction of how to setup airbags so I can lower the truck to get in and raise it up to drive with large tires. Basically the same as the low-rider look just higher. I am a T-11 paraplegic that knows nothing about the air bags but I have trouble getting into the truck.

Thanks for any help. (When one knows as little as I do about this believe me, ANYTHING is a help!)
