This might be a naive question, but I have yet to come across an answer: Since double-row bearings are much more reliable than their single-row counterparts, can a single-row bearing and spacer be replaced with a double-row bearing?

No, not with the factory width dual row as the two IMS shafts were different and required different size bearings. LN does have a dual row hybrid replacement for the factory single row which uses offset ball placements to keep the overall size the same as the single row so it will fit the shaft correctly. This LN product does require some specialized tooling for the installation however.

The tool required for this bearing is called the Faultless Installation Tool, which in reality is simply the best installation tooling for any type of IMS retrofit; but because of the unique design of the dual row LN replacement for the factory single row, it is the ONLY tool that will correctly install it without doing any damage. I literally got rid of my original IMS installation tooling after the Faultless came out, it is simply that good a tool and we use it on everything. LN rents them.

JFP, these are great news for the people that would be using the installation tool only once, because the tool looks pricey..
PS: Can't wait to see the pictures that LoneWolfGal will post of her complete and successful journey :-)

Yes. One only removes the outer (rear) seal. This resolves one of the problems with the original bearing... the seal leaking enough to wash the grease out of the bearing but not enough to allow oil back in. Fuller explanations are available elsewhere.

So it's the outer part of the bearing that's exposed to oil and not the inner part? That's counterintuitive to me, but I have yet to remove the bearing from the new engine.

In fact, both sides are exposed, but the inner meets used/trapped oil within the shaft, while the outer side gets relatively fresh oil from the sump. In that sense it's better to remove the outer seal. On the other hand, if you remove both seals (obviously this can only be done if you extract the bearing and install a new one) the oil can go freely through the bearing and won't get trapped in there.

And, you can't swap the IMS either because the chain sprocket is different.

Another that is a challenge on this othervise a very good bearing is, that I have not yet seen anyplace you could order the lockign ring belonging to the bearing groove ( pr snapring) to keep the bearing in place - or have I just missed it?
The info I got is that the snapring should not be re-used.

There was no damage on it when I pulled it out so I didn't see any risk of just re-using it.

Man, am I sick of lying down when I work under cars! After years of that, as soon as I can manage it I'm going to buy myself a 2-post 10,000 lb-capacity hydraulic lift. For around two grand (as low as $1500 on sale) it would pay for itself in convenience and time savings. And I deserve it. For the swap, though, I'll be roughing it again on my creeper.

Just be aware that ALL post lifts have a minimum thickness and load rating for the concrete they are mounte to
