Thanks, JFP! In this case the existing IMS bearing is serviceable/replaceable with the LN Engineering P/N 106-08.2.2 retrofit kit. Thus the mystery!

I'm trying to determine whether Porsche built this "AT" engine originally with the later (M/Y 2001-2004) style of IMS complex or perhaps the engine has been rebuilt a second time with these parts.
