Bagged Ratrod 1 Ton Dump Dump Truck

[BornTooLate]

My first post, new to these forums but a long time chevy truck fan. I just purchased a 69 c30 dually flatbed dump that has been residing for the past 40 years on a farm about a mile from my house. it has a 292 with a four speed and a twin piston dump flatbed on it and only 27k original miles. i am planning on slamming the truck to the ground with airbags and giving it a flat black with pinstripe paint and some other "rough around the edges" rat rod accessories, I was wondering if anyone has any experience or info on lowering and air bagging a one ton, mainly what to do with the six inch thick leaf pack in the back. I've seen a lot of info in this forum on the front end but couldn't find anything about air bagging a rear end that had leaf springs. If I'm wrong and the subjects been discussed please just direct me to the thread. Thanks!
