Rear Air Bags on my Blazer

[72BLAZERDUDE]

I am trying to install bags on the back of my 72 Blazer. Here is the problem. I have Firestone 2500s and the mounting bolts are to wide to mount across the frame at that point. Plus that is where the shock mounting cross member is so the working area is very tight trying to mount the bags and have a hole for th airline fitting to go through. I thought about mounting the bags so mounting bolts run the same direction as the frame but this causes problems with the airline fitting. I am trying to do this from under the Blazer cuz no way to get the body off. Any suggestions. Any body have pics on what they did. AirRide has a L shaped bracket that could possibly be modified to mount to the inside of the trailing arm to set the bag off to the inside of the arm. It is only 3/16 mild steel. Would this be strong enough for lower brackets?
