These are the real deal. The spindle boss is cut and welded in a higher position on the arm which lowers the car. Both have the correctly lowered Steering arms. In the 50's Honest charlie and J.C. Whitney featured these in their catalogs. The spindles allow a correct alignment. These attach to the Love Joy shock absorbers. If the coils are clamped or heated it makes a correct alignment impossible. Rapid tire wear follows. $500.00 each set
