on full driver-side compression,the pitman 
arm rubs on the steering arm, any suggestions?
Thats not the steering arm. Which would explain why I was having a hard time visualizing it. Thats the Tie-Rod, and you would have to move your steering box forward or switch to a flat pitman arm. But since the pitman arm won't work because of the frame, you have only on fix left. Which blows cause moving the box is never fun. Sorry dude.
