I don't mean to thread jack but I just ordered a Code3 pulley and was wondering how long others had to wait for delievery. I called Code3 but no answer and am anxious to get this on. Also I can't find a thread that describes the difference between shipsets. I am of the understanding that this is the third batch/shipset and that the older ones are considered better. Can someone give me a quick rundown of possible issues with the newer ones? Again sorry for off topic, but I will be using this thread to install
