Hopefully you have jack stands under the body of the car itself....and as well you let the tension off the torsion bars (undid the adjustment bolt) before doing everything else..

In that case, as said you should be able to move the lower control arm up and down by hand basically.

If the only thing holding the front of the car in the air is the contraption of support you have in the pic, get some stands under there without putting yourself in harms way for sure.
