yo BB,

Did you get the new rear leaf springs or 3" lift blocks, add-a-leafs and u-bolts?
A kit lifts the rear by the use of blocks or add-a-leafs or a combination of those. A system completely replaces the rear leaf springs and offers both better flex and better reliability. Using blocks for lift can be dangerous off road
because they can easily break or slip out causing damage to the vehicle. Replacement leaf springs are a much better way to lift the rear of your vehicle.
Adjustments in 80-96 Bronco; "...Side-to-side lean can be adjusted by about 3/8 in. (10mm) by installing a shim between the spring and axle on the low side. A Bronco that is low in the rear on both sides can be similarly raised by the insertion of 1 shim on each side. If the side-to-side lean is greater than 1/2 in., try switching the springs from one side to the other..."
