To facilitate the shock and spring installation, we lowered the height of the car while maintaining spring tension and switched out an axle jack for jack stands. Then we disconnected the shocks from the shock towers, which are directly behind the rear seat bottom and concealed by sections of carpet. To get at the mounts, we cut out the carpet perforations and the holes provided just enough space to reach in with one hand. Jose used a ratcheting box-end wrench to remove the top shock nuts. Clamping the shafts of the old shocks is also necessary to keep them from spinning while removing the nuts. GM used a nylon thread locker on the top of the shock shaft that creates extra tension between the nut and the shaft.
