Does Whiteline BTR77 rear sway bar fit the Prius III?

Whiteline offers a rear sway bar for fitting withing the rear crossmember: BTR77.

According to their info, it fits the NHP10, ZWV30 and ZWV40. I've seen it fit to a ZWV20 (Prius II) where it apparently replaces a similar but hollow sway bar, and it is of notable different shape and obviously is fitted differently than the TRD PTR11-47010 that's been mentioned in this forum.

Here is an image of it mounted to a Prius II (from the dutch Prius forum):


So the big question is: does this really fit a Prius III? Is the rear suspension of a III similar to that of a II?

 

I had a look at the underside of my Prius and yeas, it looks totally different. A bit stupid that they list it like that in their catalogue
