1975 duster K member

The sway bar is the bar from the K member going back to the lower control arm. I know that sounds dumb to say but I'm not familiar with these torsion bar front ends.

Two options there- the strut rod (green) and the sway bar (red) both attach to the K frame and the lower control arm. You may or may not have a sway bar- they were optional.
