[71 c10 rat]

i have been looking around at build threads and i want to run air bags on my truck. i was hoping to get some advice, i have never messed around with air bags before. i have two goals in mind right now, running 20's and setting the frame on the ground. hopefully you can recommend some good companies to get parts through and maybe a list of what i will need to accomplish a bagged 71 LWB. thanks for all the help i will start a build thread when i start taking the truck a part
