Bob,
In my experience CHR is not the place to buy & sell as much as it is the place for technical Q&A, advice and experience as well as socializing. In fact, all posts in the "For Sale" section get locked immediately, as they often get ugly fast. All interest is handled via PM or e-mail. If you haven't had any bites on your WTB a Swaybar I'd say no one has anything that meets your needs.
