Passenger side is about one inch down, as measured from round to frame.
It was missing swaybar link on that side-just replaced it, as the right wheel and fender liner is removed (which also means not able to check the height yet-until the exhaust manifold repair is completed).

How does one level it side to side? Have never had a torsion sprung ntruck before. Its a bit unusual to have the passenger side sag first-because usually a heavy driver loads that side and fatigues the spring. I suppose there's chance at some point a road hazard or off-road gravity-defying jaunt traumatized this side.

 

the torsion bar replaces the spring on a standard truck. The bar "twists" instead of compressing coils. The bar is probably 4 feet long and anchors in a HEX socket under the driver and passenger seat area. There is a cam and setscrew on th end of each bar. You crank the setscrew in and it "twists" t he bar and causes the truck to rise up. The screws are metric, maybe 14 mm heads or so.... look at the cross brace under the seat area at the back of the torsion bars. YOu should have 3-4 threads showing on each screw. Couple turns will give you close to an inch.
