The fork has the normal little hole in what would be the bridge. If I remove the brake, I can get something in there, but the wedge or plug will still be in there.

In looking at this option, I've come to the conclusion that the wedge didn't drop after all or maybe doesn't drop now. If I tighten the stem bolt and pour Kroil into this hole, with the bike upside down, it does not come out the top. If I loosen the bolt, it does. Bike is presently upside down with Kroil in the steer tube.
