Pitman arm is hitting tortion bar! Help?

Just a little update..got the lca bushing in the lca and ready to be put back in the car as soon as i can get that k frame welded up. I have a moog k7076 pitman arm coming tomorrow morning from a local parts shop. and i have that mopar performance chassis book coming one of these days then i can start reassembling it. I have been really searching and looking around on the internet about why im having this problem and ran across another thread about a guy that was having the same problem with his 73 challenger. He said he shimmed the top two bolts on the steering box and had to go through three different pitman arms before he got it to work..so i guess ill keep my fingers crossed and see how it goes back together :D. Thanks for everyones opinions and suggestions again!!
