73 duster lower control arm adjustment

I have a 73 duster that was a roller, now I have put the engine, trans, and all the body parts on it and the front ends sits too low. I need to raise it up 2-3 inches. My question is how I can do this? I thought that I could adjust the lower control arm adjusting bolt as it sits, but I cannot turn the bolt, even with a 6 foot bar on my torque wrench. Is there something I am missing or do I have to unbolt the upper control arm and adjust it that way or should I be able to turn this bolt with everything hooked up? Any help would be great.
