AT in engine number

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.

So you already knew they're not always the same.

I didn't have the luxury to see which bearing was in the car. I had a really short window of opportunity when the transmission was out for the rebuild, so I had to order everything in advance before taking the car to the shop. Thankfully, Pelican Parts graciously took the bearing back. I can't say the same for LN and the tool I couldn't use.

I just wanted the OP and others to know, in the event they decide to service the IMSB. Peace.

No, the engines ARE the same, only the IMS shaft has been changed to the updated version. But if it makes you feel better, be my guest.....................

They're the same but depending the build date, you can or cannot service the IMSB. Ooooookay.

You can tell them what you want. I just wanted them to know that, if they intend on replacing the IMSB, they MAY NOT have same type that originally came with the car. And, if they've been following, I'm sure they understood.

Which is why it would be THEIR responsibility to find out what they are dealing with before they order parts they may or may not be able to return.............

....because it's not always the same. If it was the same that came with the car they wouldn't need to, would they? Just sayin'.

Look, ALL the necessary information about which type of IMS could be in the engine is readlly available to ANYONE that takes to time to look and do some reading. If one choses not to do that, mistakes can be made, but not because this is some kind of mystery, it was by choice........
