You aren't going to know that until you actually go to do it. It's all manufacturer tolerances, as has been said a number of times. No two bikes are the same, so for someone to say that every single 2003 model is going to have to grind, is inaccurate, and to say that all 2004 models won't have to, is inaccurate. Just go ahead and do the mod and figure out whether yours has to be ground down or not. That's the only way you are going to answer your questions.
