C20 Rear Airbag Suspension

[RuinCreek350]

So I'm thinking about using airbags for my '71 c20 chassis in the rear and maybe the front. Currently it has 10 leaf springs on each side and it is way stiffer than i need it to be. My truck is a frame off restoration that I'm doing. It will be a daily driver with an ls swap. I'm looking to keep the stock 3/4 ton height. If anyone has any information on compatible kits or has done this themselves to their truck any recommendations or any info at all would be greatly appreciated. -Thanks!
