Wrong!
The W126 sway bar will not interchange with the W123. I pulled the rear sway bar out of 2 W126s at the yard today and compared them, they were the same between a Euro 280SE and a 300SEL. I bought one and came home and pulled the bar out of my 240D. The W123 bar is about 2 inches more narrow than the W126 bar both at the Z bends where the mounts to the body are, and at the ends. I tried stuffing it in anyway, but the bracket mounts on the W123 are indeed to narrow.
Now I have to go put my old one back on. :|
Edit: my stock bar seems to be 13.5mm because I can not get a 13mm wrench around it, but a 14mm fits with a tiny bit of slop. Also both W126 bars seem to be 14MM, not 15, as a 14mm wrench will fit around it tightly. (Notice the gap between the 15mm wrench and bar in the picture above.
