I'd be carefull with those old style Airlift bags. They are REAL soft and have a tendancy to pop out the endcaps if you bend them too much...front ends of the squarebodies bend a bit. The crimp rings don't take too well to stressing, and will fail over time if they are bent alot.
They are good and get the job done, but you have to know their limitations. I have used tons of these bags and won't run the old ones anymore.
Now don't get it twisted, the above bag was still working after four years, but you get what i'm saying. Plus the front end setup that was being used was a little sketchy...we changed it and put Airlifts new Dominator bags in...they work great!
The reason I would NOT use the now Dominators up front on your rig is cause of the type of setup you are currently running. The new bags will give you retarded amounts of lift, but will still balloon. Space looks to be at a premium with your current setup...use slams, they are stiffer and retain their shape better.
Don't get me wrong, I think that they make a quality product and I have had no problems with the guys at Airlift accepting warranty returns, but I would look into some slams with the front end setup you got going on. The Airlifts will balloon more than slams will, and if you are running that kinda LCA front...i'd be weary...my 2cents.
