Well, yes and no, so you can at least have hope that your search isn't doomed to frustration. I bought a pair used here on the forum some years back and they do what you want, although the also raise the bars about 3/4". I found this site that shows them, but they're very hard to track down; I've looked for other sources for them and found lots of dead-ends. By the way, they do fit my '05, so they're also ok for your '04.
I wanted them to pull the bars way back toward me--much more raked than the stock look. Mine are so far back, in fact, that they're sometimes a little hindered by my tank bag, but I really like not having to reach and lean for the grips. They rotate through maybe 30-40 degrees of travel and then lock down with an internal setscrew. You might be able to find some--can't say, but at least they exist.
