Rt Front Corner down 1 1/2"

I think I need to adjust my right front torsion bar as I do not see any suspension damage, bent or broken. What is the procedure. I check on line and everything points to the rear of the torsion bar for adjusting bolt and nothing there. The bolt seems to be on the front below the lower control arm. Need to confirm and any special tips. I need to go up 1 1/2 " on the right front.... thanks
