Maybe you can give me a hand to get the right set up.
Regarding the ART kit if this arms only help for alignment then it's a way too expensive I think. My idea was that they give me an additional drop and more claerance under the truck.

As I mentioned, I don't have any experience with the Strong Arms, but I've heard that they don't buy you much clearance. I would guess that they do offer some (just a bit of) clearence since the flanges around the LCA hang lower then the tubular arms. (A few folks in the 67-72 section have experience with them.)
To answer your other question, here’s a quick rundown:
To start off with, you could use the cups and brackets for single port bags that Suicide Doors offer for the 67-87 trucks (
http://*****************/67-87Fullsiz...Brackets.php#).

The upper bracket mounts to the outer flange of the spring pocket on the crossmember with 4 fasteners. The cup installs in the spring pocket of the LCA without the use of fasteners. You may want to section about 1 inch out of the cup to have the bag sit lower in the LCA without risking the air bag rubbing on any surrounding components, and thus lowering the ride height in the front. For this particular application, you should go with a double-convoluted style air bag. (vs. the sleeve-type air bag). To handle the weight of these trucks, the Firestone 2600 model (224c) is a popular choice. They are available as a single port bag. (Unless you are setting up a very radical system, I don’t see a reason for dual port bags.) They are set up at a ride height between 5” – 5.5” and can handle a weight of 3,150 lbs. @ 100 psi. The specs for Firestone air bags can be found on the Firestone web site (
http://www.firestoneindustrial.com/r.../cscinfo.shtml) as well as on the Air Ride Tech (
http://ridetech.com/productinfo/dimensions.asp). I can’t find the exact pdf that Firestone put out their air springs quite a while back. BTW, the Firestone site has some good information on installing and maintaining the bags as well.

Although, Firestone is a popular choice, the double-convoluted bag offered by Slam Specialties have a strong following. They report that their bags don’t ballon like most traditional air bags and they are also more responsive as well. I’ve heard the ride is bit more firm than the Firestones. Their 7 series is a direct replacement for the Firestone’s 224c. You can found more information on the Slam Specialties web site (
http://slamspecialties.com/). BTW, their bags are designed with a higher pressure rating.

Next, you’ll need DOT-approved air line and fittings. Among the choices for the size of the air line and fittings are 1/4”, 3/8”, and 1/2”. You may find a slow rise and deflate time with the 1/4” and too fast of a rise/deflate time with 1/2”. (Although, you can install rise/dump controllers to slow the air time of the 1/2” lines.) Then, if you want a fully automatic management setup, you’ll need to get valves like the ones that SMC offers, an air tank, a compressor, gauges (and 1/8” line) to read the pressure of each air bag and the other components (switches, leader hose, pressure switch, check valve, water trap, etc). Suicide Doors as well as many others offer a good selection. If you plan to maintain the air bags at ride height and not have a need adjust them on a regular basis, then you could forego the ‘accessories’ and plumb the air bags with Schrader valves installed on the ends of the air lines. Then, down the line, work on completing the system. Regardless, each air bag should be plumb independently of each other.
