I'd be VERY interested to hear what Gary has to say after he opens up an '04 and has a look. If you look at the A-Arms between a 2001 and 2003 (comparing my two DS') you can easily SEE there is a dramatic change, not to mention there are other suble changes - some of which caused the from wheels with inner rings from my 2001 DS to not fit on my 2003 Baja for example. The kicker is that again, Bombardier said there was no change in the A-Arms, yet the machines handle completely different (even if you swap tires.) There are times when a company WANTS to release info about changes, and times when they don't. From what I've seen Bombardier is very quient when making the 'small' changes.
