front end adjuster adjusting

[zen]

the car is in the air. i swapped the short shocks for standard height ones. and have those removed at the moment too. i assume this to be a standard height beam. i did not try to actually turn the adjusting bolt, just backed off the jam nuts and the bracket. i assumed turning the adjusting bolt itself would remove it from the torsion bar which is under load. is that the way to adjust the height though?

maybe instructions would be good.
