Pitman arm is hitting tortion bar! Help?

i just read every word of this thread, congrats to OP and all you guys for the great support.
a quick question for all of you since my friend is having some pitman arm issues, are the manual and power steering arms different? if not, he's probably got a pitman from a bad batch.
his car is a 69 valiant with a 74 v8 k-frame and corresponding parts, but he's running a manual box that was on his old /six k-frame.
thanks- pauly

edit: found the information i needed, thanks!
