Using a 14mm socket (a deep-well or 3" extension simplifies the process), remove the single bolt from each bracket. The brackets will tilt forward from the top. Pry them off the bushing, and slide them out of the lower slot. Keep the 2 bolts, brackets, and bushings if you ever intend to put the stock bar back on the car. With both brackets removed, the bar will be hanging loose, held only by the end-links.
