Torsion bar help 1970 dodge dart.

As for the 'wrong clocking'... as, they installed the bars 'one flat' off... think about how much angle one flat is to the next one...: it's a 60 degree angle!
IMO there's no way you can 'mis-clock' a (thicker) torsion bar and still get the LCA/suspension bolted together again.

If the PST bars have a 20° twist for each L and R bar, then it's way more likely the bars have been switched left to right.

I promise you can mis-clock a set of larger torsion bars. I did it myself with the 1.12” bars in my Challenger the first time I installed them. It can in fact be done if the indexing doesn’t put a single flat right in the middle of the range of travel of the LCA. One flat at the top of the range of travel, the other at the bottom. This is even easier to do if you have tubular LCA’s, because they will hang almost straight down on the LCA pins and not hit the K, unlike stock LCA’s.

And that assumes you have the adjuster levers in the right place during installation. Like I said, it can be done on at least some larger torsion bars. Maybe not all larger bars, because it is indexing dependant, but it is possible with some.
