They install on the rear just like any swaybar endlink would. I can't get pics because I haven't owned a six in over a year, but perhaps someone will be nice enough to post some pics.
The rear links are the same parts as the front except adjusted to be the correct length and have both rod ends facing the same direction. Install is super easy. Unbolt (or grind, cut, burn, nuke whatever it might take) the stock endlinks. Put the new endlinks on and enjoy how much easier it is to just use two wrenches to tighten them down instead on an hex head.
Its 4 bolts total and perfectly straight forward
