Appreciate everyone's feedback. I neglected to provide additional info:

I'm the 3rd owner
70K miles
IMS not problematic
Replacing AOS with engine/trans drop so performing preventive maintenance while the engine is out: clutch, starter, crank seal, plugs, thermostat, hoses, etc.
Planned to replace IMS bearing as well, but it appears that it was replaced. I don't have any record of this being done. I have the maintenance book, but not entry. Had routine overservice work at least annually.
I've put 20K over that past six years; no driving in the winter; MI snow
I change oil and filter twice annually and always before I prep for its winter hibernation
No mechanical issues since ownership

Here's a pic....each bolt and the center nut had torque seal placed on them.

I'm not interested in providing the prequal check list information, which seems excessive. I understand liability. I'm performing all of the work myself so I am searching for a IMS solution that is straight forward and reliable.

The flange bolts and center bolt are open to oil inside the crankcase - hence the thread sealer. This is a normal part of IMSB replacement. I'm interested in why you would disregard the pre-qualification process, as it's meant to protect you in the long run? By the looks of the flange and the surrounding area, it's been cleaned up quite a bit - was it leaking before?

Is that dual row, single row, larger bearing? And what is meant by, '2018 onward'?

This isn't a one size fits all condition. I did check that part number at Sunset Porsche's site. Very little detail. They list it as an "As Bearing Shaft". What the hell is that?

^^ That would be the IMS (Intermediate Shaft) itself (including the bearing) - I'm pretty sure this is how they sell it (not bearing by itself - though they apparently did sell the bearing & Flange for a short period of time).

That makes some sense. Still not clear which application it fits.

I recall seeing a post by either Jake or Charles where they bought a genuine Porsche IMS bearing from a dealer. As part of that post, it was shown to very closely resemble the LN retrofit, right down to the ceramic ***** (IIRC) and an almost exact duplicate of the flange. It was noted that, that part was only available as a dealer part for a short period.

No
That is the part number for the bearing itself. Single row. Latest version from Porsche. Available since late 2017-2018.

Flange would be 996.105.124.80

The price I saw for that part would not reflect the IMS. We still don't know the application. Single row could be 2000-2004, right? If it's the larger bearing, then that's a different application as well. I don't believe they are interchangeable.
