yah let me try to post said video.
Just installed the same setup (RB links, FM sways) and had a mystery "clunk" form the rear when turning. Turned out that one of the endlinks did not get tightened all the way down, so the swaybar was sliding back and forth in the bushings... the noise was from it contacting the rear subframe. Check around the bushings, I had a little grease get smeared out on the sway on either side of the bushing from it moving side-to-side.
