To adjust the front ride height you will need to measure the difference of the height between the outer and inner pivot points on each of the lower control arms. If there is a difference you will need to increase or decrease the thickness of the rubber on the top of the springs.
The BBB spells out the procedure.
You can order the correct spring rubber form Classic Center.
