The 20mm rear swaybar(top) from the TL will bolt up. I just installed it on my cw2 wagon. It slighlty rubs on the subframe but it doesn't vibrate or make any noise. Idk if the wagon subframe is thicker than the sedan but a 19mm should fit without issue. The bar came from a 2010 TL typeS. It came with bushings/brackets. The TL sway bar brackets are Identical to the oem Tsx brackets. I'll drive it around for a few days and report back about the rubbing.
