I found a set of front/rear GD (2004) STi sway bars in my shed, so they're up for sale. I've read around on the net and found a few sources that say they are both 20mm, but doing the dodge and measuring them with a ruler makes them look more like 19mm . . . I'm not sure, either I should be using verniers or maybe the size varies throughout the years.

Either way they were a good, budget handling upgrade for my Forester before I went for further mods. They'll fit all GD WRX/SG Foresters (I've heard of people throwing them on GC's as well, but that's up to you to figure out).

If you're keen for photos just let me know, but I reckon we all know what standard swaybars look like.
