I recently replaced the freehub on an early 105 hub to go from 7 speed to 9 speed. I actually bought a Sora 8sp hub for 12 dollars, and then swapped the freehubs. Now I've got a 7 speed sora hub, and an 8/9/10sp 105 hub!
9 speed gear is easier to find, and in some cases cheaper, than 8 speed, and uses identical freehubs. I respaced by moving a spacer from one side to the other, and then redished. I had to space my old frame from 126mm to 130mm too, but that was a small change and easy to do on a steel frame.
You can buy just a freehub, or any cheap 8sp shimano hub, which will have the same freehub. The cones and axle were the same between the sora and 105 as well.
