Torsion bar install question

One consideration is the lever/finger on the control arm that the adjusting screw presses against.
Years back I bought a set of 1.15" torsion bars from Bergman Auto Craft. He had some surplus bars from XV Motorsports.
On Peter's advice, I aimed that lever/finger level with the ground and the torsion bars slipped right into place.
Now, this was probably because the 1.15s are so thick, they don't need as much preload with that adjuster to get to a desired ride height. Still, this was a good nugget of advice that served me well.
