Can I ask a silly question?..... Why are you trying to level out the car with one new torsion bar and one old? Is there a reason you haven't installed both new PST torsion bars before trying to level things out and reattach the sway bar.
What size is your old torsion bar that is still in the driver side? Not trying to question you, but I'm curious why you aren't putting both new bars in before trying to get everything leveled out. Not sure I'd even want to try to drive the car with a stock .8something" stock bar on one side and new PST 1.03" on the other.
When I did mine on my '67, I replaced both at the same time (with Firm Feel 1" bars), then adjusted to have the correct ride height and so that it was level.
