I'm pretty sure that's not a 1969 pitman arm. For a pre-'73, the stud should pointing up through the center link. Not down as shown. Moving the joint below the center link could free enough room to clear just the stud and nut. Same with the idler arm. Of course someone may have swapped in the '73-up center link, which would leave you looking for an earlier one.
Anyway, before I raised the devil with TTI, or took a torch and hammer to the pipe, I'd try to be sure what is supposed to fit is actually in there.
