I am trying to find a way to install airbags and a 4-link on my 47 chevy truck.I would like to use most of the stock parts,in other words. stock as possible  

for the front you would have to go ifs, no other choice really. how low are you trying to go? if you want to save money you could go mono-leaf in the rear, make a c-notch and mount the bags to the axle. this means no for link in hte rear, lift up higher than stock and drop much lower and ride like a normal air ride set-up. then theres always the s-10 chassis swap. thats what i did on mine no bags yet not enough money but that is the plan. hope i was of some help, if anymore questions let me know.
