Clocking lower control arms and PST 1.03 torsion bars. 72 Dart

Typically with large torsion bars you install the bars with the LCA's positioned close to where they will be at ride height, not hanging all the way down against the K frame like with the factory bars. It depends on the built in offset of the bars though. Large bars with zero, or near-zero offset will only install with the LCA's lifted up near ride height. I'm not sure what the offset on the 1.03" bars is now, I know it used to be zero but that changed when too many people complained about not being able to get the cars all the way back up to factory ride height. The factory instructions are for a torsion bar with 20* of built in offset.

That is correct that they "used to be zero clocked".
I made sure I got the newer ones that are OE clocked on the hex offset.
They all only go in one way, cause there is NO way you could get them off by a whole hex flat without it being really obvious.
