...and if you can't find someone to swap with and your steerer is too long (meaning after cutting there's not enough thread to work with) you should be able to take it in to a bike shop and get the thread extended as far as you like
I just did the same with a P2 I had that was far too long and after trimming it to size there wasn't enough thread. LBS had the tool's to thread it, a simple and quick job, and voila, perfect length!
...so when in doubt, buy too long as opposed to too short
