Jon- Sorry to hear of your loss. Perhaps a local shop will spot the bike and recover it (as I did to a friends bike a long time ago).

You can make a drop hole fairly easily. Two strips of steel with a couple of holes in each and a piece of tubing is all it takes. Run a bolt through one of the holes on each of the strips, sandwiching the frame's brake hole. Place the piece of tube between the still exposed holes that are now just below the brake bridge and place the brake center bolt through this and presto chango you have the brake mounted lower then before.

I did this for a few bikes when mounting Campy side pulls when the bike had longer reach centerpulls originally.
