I know I've seen this somewhere before but I'm short on time right now. What is it that tells you if a T5 is a World Class or not? I'm pulling my broken one out and I wanna make sure the shop that I got it at a couple years ago didn't screw me over. I have reciepts and everything saying I paid for a World Class and if its not one I'm taking this one and throwing it at them, ha. Any help is apprciated. Thanks.
