The factory Touring cases fit fine. I have an extra set of brackets, make offer. You won't be able to lift up the seat without taking off the right bag, but otherwise they fit fine and carry a lot of stuff.
To remove the black dash panel, use snap-ring or needle-nose pliers and carefully unscrew the nut around the ignition switch. The dash is then held in place by two small tabs at the lower front corners and two rubber mounts up near the top on each side. Carefully press inwards on the front lower corners of the black plastic where they meet the red cowl, until you can pop up the lower corners of the black piece just a little, just separating it from the red cowl. You can see the tabs by pressing in a little. They fit into recesses in the red piece. When you have the lower front edge released, just pull the whole thing up and back and the rubber mounts will release. They fit into C-shaped recesses on the back of the dash.
The wiring harness for one of the turn signal bulbs (left?) is a little short and the plug only fits one way. It's a pain to get your fingers under there (mine at least) to push on the connector while the dash is half-way installed. Just persevere, or find someone with smaller fingers.
Good luck.
