My 69 body off restoration...got a question!!

[gofast loudstacks]

Im 19 and just bought a 69 chevy c10 the outer shell of the body is in awsome shape..but it was a farm truck..so the floor and the suspension and the whole bottom of the truck is rusted out...I got that covered. A one peice floor, rocker panels, cab corners, and door skins, will take care of the rust..I had a question for those who have it...im lookin to do a air ride system on my truck since im replacing the suspension anyway..nothing fancy..i just want that low look that i can adjust so i dont screw up the truck when im driving..and when i can lower when im stopped for show..I want to know of any affordable reliable easy to install/ fabricate air ride systems and where i could find them...thanks for the help.!
