1973 Duster 340 Torsion Bars - recommendations

When you say indexed properly what are you referring to? I have the left in Drivers, right on passengers. Also, when I go to buy the bars, it says clocked at 15 degrees or 20, etc.. I removed them, by loosening adjuster all the way flush, remove bottom bolt of shock, push the suspension down and slide bar out using torsion tool. (Couple of taps and it slides out) Lower control arm at about 4 o'clock angle. Should I clock to the next hex? If I do, it seems like almost at 6 o'clock position seems a bit extreme on the angle to start. This is driving me crazy, which should be so simple.
