Not to be pedantic, if the serial number for your AT engine showed assembly before 2004, it would have had a single row, serviceable IMS bearing; if the date were 2004 or later, it would be carrying the oversized bearing. If the date of assembly came back as late 2003, standard retrofit practice would be to look and see which bearing is in the shaft before ordering parts, just to be safe and not waste time and money as there was definitely some overlap during the changeover.
We do this for a living, so we have seen most, if not all, ways one of these retrofits can go sideways and try to avoid those pitfalls.
