Installation of Sway Bar (optional step): Our project car did not previously have a sway bar (most sharks would not), but we chose to add one for enhanced performance. Attach the sway-bar mounting plate to the top end of the trailing arm by drilling two 1/4-inch holes through the top end. Space the holes according to the bracket. Then bolt and nut the mounting plate in place. Attach the urethane bushing approximately one inch from the 90-degree bend on both ends of the sway bar. Hold the sway bar in approximately the correct position and youll note that two factory-placed nutted holes are preexisting in the frame. Place the urethane bushing so that it falls between these two holes, cover the bushing and holes with the mounting bracket, and bolt in place. The ends of the sway bar must be above the sway-bar mounting plate. Jack the trailing arm/spring assembly up to the sway bar, and by pulling the sway bar down some, youll be able to get them within a few inches of one another. Then, bolt them together with the end-link bolts. Correct placement of washers, bushings, and spacers is important: bolt, washer, bushing, sway bar, bushing, washer, spacer, washer, bushing, mounting plate, bushing, washer, and nut. Tighten the nut approximately 1.5 inches onto the bolt and release the jack.
