Z-Bar and Clutch Rod Linkage won't line up. Help!?!?!

I have a 70 Duster, 360, 4 speed. When I install all of my linkage, the z-bar and clutch rod linkage do not line up. What's happening: the arm/lever that the clutch rod attaches to is about 1-2" left of the clutch rod. Meaning, that arm needs to be moved in closer to make the clutch rod linkage line up perfectly straight.

Am i using the wrong z-bar? Do i need to just re-locate the arm? I'm assuming I might have a /6 z-bar but have no measurements on what a /6, small block and big block z-bar are?

Any help would be greatly appreciated!!
