My posts will now jump back to the start of the entire project.....the chassis.
The chassis had already been changed by someone else before it came to me. Mainly they installed an aftermarket Mustang II style front crossmember with air ride. Out back, they had kicked the frame up and put a Ford 9" with a triangulated air ride setup as well.
The front was pretty good for the most part, just a few minor changes / corrections were performed to clean things up a bit. The rear was a different story all together.
The first basic task was to make the front air bag setup a bit better. Hard to see in the picture but I curved the side of the frame rail in next to the airbag as initially it was rubbing the frame rail. As you can see there is good clearance now.
Secondly, I didn't like the mis-alignment of the bag while in the "ride height" range. So I moved the bag mount out on the lower a-arm (it's mis-aligned in this picture still)
Here is a comparison of the change in mounting hole for the air bag and also how I added to the lower mounting pad a bit.
Now you can see how the bag is more "relaxed" and aligned while in the ride height travel range of the suspension.
This picture shows the bag fully deflated and why I added the extra surface on the mounting pad. Previously the edge of the bag hung over the metal edge and would have been a prime location for chaffing / damaging the airbag.
When the suspension dropped full "air out" the steering tie rods interfered with the bottom of the frame. I notched in a tube to allow good clearance.
