Rear anti-sway bar for 4000Q?

[VFChris at aol.com]

Hi list,

Does anyone know of a cheap solution to add an anti-sway bar to the rear of a 
4000Q?  Blaufergnugen (perhaps others) offers a new one for about $290, but 
I'd like not to pay so much.  

As a thought, does an anti-sway bar from some other car like a CQ or 90Q20V 
fit on the 4000Q?  This could then be purchased used.  I assume one from a 
UrQ would fit, but there are certainly not many of them that have been junked.

Any thoughts would be appreciated.  Please send to me privately as well as to 
the list.

TIA,
