Rich stated the fact that he always receives 712 racks from zhp owners no matter what. This isn't just like 40 racks. It's quite a few. I do agree that it would be better to get a reading on exactly how common the 712 rack is outside of just the performance package. But according to rich, all 3 racks were available on 2002-2006 330s
He's the expert so ill take his word. I will edit the post as more information becomes available. But I just wanted to get the basic, usable information out of this thread and compile it into a crap free thread.
