Step 1)  Raise the front and place the car on jack stands, removing the front tires at this time. Step 2)  Remove the front shocks and mark the lower trailing arm with a reference line on both the trailing arm and the end of the torsion bar. Step 3)  Remove the nut on the end of the upper ball joint, and seperate it, repeat for the lower ball joint.  These nuts will be very tight, as the torque spec is 80 ft-lbs, so you might need a cheater pipe. Step 4)  Loosen the nut on the grub screw, and with an 8mm allen wrench remove the grub screw from the lower trailing arm, and then remove the bolt and keeper just above the trailing arm. Step 5)  Pull the lower trailing arm off (some have reported using a puller for arms that were rusted together), and using the reference mark as a guide, set the desired spline drop.  Raise the arm to drop, lower the arm to raise it.  Note each outer spline equals 9 degrees or about 2.5" of drop.  Most drops are 2 splines, any more than that, then shorter shocks are required.  Reassembly is the reverse of the above disassembly proceedures. Be sure when completed to have a front end alignment done as soon as possible, as the car will have at least 1" of toe out and this will eat the front tires quickly.   I hope this helps.
