I did this not too long ago. I also wanted to get rid of the rally ride height. Once I had the spring plates at full droop, I measured from the floor to the lowest point on the spring plate. So, if I wanted to lower the car 1 inch, I just added 1 inch to the measurement and got the spring plate indexed on the torsion bars as close as I could. When all said and done, I was what my mechanic called "dead nuts on". I was lucky. Also, getting the torsion bar covers on was an ordeal itself. The first time I put one back on , 3 of the 4 holes would not line up. I got some advice to purchase some long bolts with the same thread pitch and some medium length ones. Start with the long and tighten down each one little by little. Then switch to the medium, the original. Worked like a charm.

Good Luck!
