Thread dial

Hi, my thread dial fell off of the thread dial mechanism (it's just a thin metal cap). Not the entire mechanism, just the little dial itself (it was just glued on). Is there is specific location that it goes back on, or can I just glue it on without regard to where it was located before. There does not appear to be any glue markings that will index the dial to top of the thead dial mechanism or I would have just glued it back on in the original location.
