QA1 K member (67-72) in a 74: Pitman arm hits torsion bar

I need help figuring out why the top of my pitman arm and tie rod end is hitting the bottom side of my torsion bar. I know people have done this before, putting a QA1 k in a 73-76 car. The guy at QA1 says it might be the pitman arm because its for a large sector shaft and not a small sector 67-72 box, are the pitman arms any different in their shape? Also, I don't see how it can be that because the idler arm clears the passenger side torsion bar with no issues. However, one thing to note is that when I torqued the k member to the subframe, the way in which the car was jacked up may have caused the subframe to be crooked but I can't see that causing anything since I had it aligned perfectly.

Here's the parts I have:
74 Duster
QA1 K member for a 67-72 A body
Large sector shaft steering box 73-76
73-76 center link and tie rod sleeves
73-76 pitman arm and idler arm
PST Torsion bars
Factory LCA and pivot shafts
Polyurethane LCA bushings

Are 67-72 pitman arms the same shape as 73-76 pitman arms?
