Sorry, coilover/strut. I worked for a company that built those (including the OEM shocks on my 4Runner) and we called them modules, old habit.
I finally got a hold of someone at Toytec and they straightened me out. They are different somehow, but if you have Toytec assemble them, the guy who does it will mark the bottom of the bushing loop with "DS" or "PS" for driver or passenger side. Toytec did not elaborate on what exactly the difference is.
The top mounts are also at an angle due to the spring, so it helps to try different orientations for the upper mounting until you get one where the lower bushing is close to the LCA shock mount.
