Rear bags?

[Wootdog]

I joined what I think was a old post on the suspension forum. Not many people are answering up do to the fact someone else started the post over a month ago. I am in a dilemna at this time. As you all know I recently got my 67 stepside on the road. Well I am at the point that I need rear air bags at the least. My brother who started working on the truck about eight years ago set it up for bags with a F**d nine inch rear end. It has the buckets for bags already there. It bottoms out enough with shocks to knock out your fillings in your teeth. I need the bags fittings, air lines and a tank I think at the least. With the fact I know nothing about any of this, I would like some input about prices, how hard it is to install, and with the fact I am getting burned out working on the truck what a shop or individual might charge for the installation. Any help or input from you great people would be appreciated. Sorry for the spellings but you all know it is New Years and I am celebrating. Thanks in advance. Kerry the Wootdog.
