928 S4 Rear Sway

[Clatter]

Looking at rear sway bars, and the diameters..(Thanks Pillow)
The biggest 944/968 M030 rear bar is 20mm.

The 928S4 has a 22mm rear bar(!)

It does look a little different than the 944 ones...

Especially the mounts, but it seems that the mounts could be changed.

Anybody out there ever look at the 928 stuff?
I vaguely remember the rear arms and brakes being the same, so why not the sway?
It really looks different in the pictures...
Can it possibly be made to fit?
