Got the rear springs and rear sway bar extensions installed. Broke three out of four rear upper shock bolts. Left my air hammer at my brothers house, he gonna bring it in the morning. WHAT A STUPID DESIGN! Read a lot! If air hammer doesnt pop the welded nuts off, looks like im gonna have to lift the body up enough to grind them off. Also looks like i might need a bracket for the rear trac bar (the zirk fitting hits the factory bracket on axel side). Im in no hurry and working solo, so i didnt start on the front yet. The rear bumpstop extensions went in very easily. If anyone has a simple solution for the rear shock upper bolts, please chime in!
