Planning on changing diff oil, trans oil and flex discs in the near future. Looks like I can probably do rear diff on the garage floor, but my friend has a 2 post lift. There appear to be 4 jack points just inside the rockers. Am I correct in assuming lift pads can be set there? I remember reading about Solstices and Skys getting messed up, because they needed special blocks inserted before being put on a lift. Just want to make sure there aren't any gotchas before getting started...
