Finished installing the passengers side ShockWave today. Like with the drivers side I removed the bump stop cup, trimmed the corner of the bracket, shortened the sway bar end links 2 1/4" and drilled out the end link nut to accommodate a 3/8 bolt. From GM the bolt/nut is 9mm and the ShockWaves came with a replacement (shorter for the shortened end links) but it was the wrong size. I didn't have any 9mm hardware laying around but did have a few 7" 3/8 bolts and nylock nuts that worked perfectly.
Here are a couple pics...
