Ladder bars/stock frame/rear coilover length?

I have no idea but, I like where you're going!
I recently installed a Moser fab 8.75 with a backbrace, Dr. Diff offset front hangers, and Mopar SS springs. I moved the rear back an inch to get a bit more tire clearance, but with the backbrace, the stock shock mounting location wouldn't work. I was in the process of fabbing up a new mount in front of the axle when......, my buddy "talks me into" putting ladder bars on. Pictures of wheels up launches danced in my head, but......there's not a lot of room behind the axle for a coilover upper mount. Even less when you move it back an inch,.......and have a backbrace. Looking at the Summit Racing double adjustable coilovers - about a 10" compressed/14" extended may work but a little input from someone who has chartered these waters would save this poor guy with 10 second dreams a little heartache.....and $!
