Torsion bar direction

Front to back makes absolutely -0- difference, other than which markings You want to see through the back of the anchor sockets.
Right & Left DO matter, these bars aren't just chunks of billet steel or something, they are formed in a spiral-wrap fashion. R&L are wrapped in opposite directions when formed, besides any clocking, if they're not marked I'd be surprised....or suspicious..

Hmmm. The MP bars that didn’t have a hex offset (zero index) had a single part number, no left and right because the hexes were flat to flat. The old PST 1.03’s were the same, zero index and no L/R.
