IMO the right thing to do is cut down the steerer, but that requires a modicum of skill and proper tools. But you only need to cover a few threads. If you were in the greater Portland area I'd tell you to swing by, I have a lot of spacers I'd give you. Search for headset spacer 1", you'll find many online sources, or just go down to your LBS.

Which brings up another point, it's a good idea to post your location, you could make some new friends with tools and knowledge to help you out.
