Why does the left rear hang low ???

If the left rear is low the right front is high. Great thing about torsion bars is ride hiegth can be re adjusted over and over again. Coil springs (GM) need spacer blocks between the coils.

How do you lower the right front torsion bar ?? I must be confused on my parts here, cause it seems the torsion bars could only adjust fore and aft.. Sorry to show my ignorance, but can someone tell me how to do this in laymans terms ??

Thanks
