EDIT 2 (addendum):
To answer my own original question: "Will the stock (17mm) RSB bushing brackets fit 22mm RSB bushings?"
For anyone else interested...
The answer is an absolute: NWIH! (no way in hell!)

You're welcome.

EDIT 1:
Nevermind - I contacted the supplier and they confirmed that the Alta ARSB I ordered does come with new bushings, brackets/carriers and lube.

Original question:
The short version:
Will the stock (17mm) RSB bushing brackets fit 22mm RSB bushings?

The long (and stupid) version:
I had posted a question a while back concerning a soft clunking sound coming from the rear of my '04 R53, while driving slow over speed bumps and uneven/lumpy roads.
I was getting ready to install new rear (OEM 17mm), swaybar bushings before I came across a great deal on a new 22mm Alta ARSB for under $200. I soon realized this RSB does not come with bushings.
So I ordered a set of 22.3mm Power Flex RSB bushings. Only to soon realize the bushings don't come with mounting carriers/brackets. Anyone know if the stock RSB brackets will fit the 22mm bushings?

Thanks.
