upper a-arm air bag plate/mount question

[old_blew_72]

i'm wanting to bag the front of my c-20. last year i put bags on the trailing arms but kept stock ride height, i wanted it to pull good and be able to load it heavy and not have it ride like a c20 if you know what i mean. i built the trailing arms and bag mounts and i figured since i've got plumbing to two bags what's two more. anyway i'm looking for something like this, i think it's pretty popular, but i want to build it myself.
