How can I know if two lenses have interchangeable elements?

This simple question might have a not so simple answer, and I want to ask it about a single lense, but assume that would be off topic, because I'd basically be asking 'should I buy this to repair my other lens?'
Here's an example: are the lens elements from the nikon 18-55mm vr ii compatible with the elements from the 18-55mm vr? They look cosmetically similar.
Is there a spec sheet?
Same with other lenses, like the 50mm 1.2 ai-s and 50mm 1.2 ai. Compatible elements? Spec sheets?
My example comes with real world motivation: I got a free lens from a friend, wanted to try my hand at repair for cheap. I saw a lens with the same specs, same generation, but one model newer or older and it's af motor is damaged, or something similar.
Feel free to edit my comment if you feel it can be better phrased.

It would basically be impossible for anyone other than the manufacturer to answer that question about any given pair of lenses. Two very similar lenses might have some of the same outer elements (particularly the front lens, which is the most commonly damaged part), but they could also be subtly different.
For example, the Canon 16-35 L, L II, and L III look almost identical, and both have 16 elements, but
- L: 10 groups, 14 elements, 77mm front thread
- L II: 12 groups, 16 elements, 82mm front thread
- L III: 11 groups, 16 elements, 82mm front thread
You probably should assume that the lens elements themselves are not interchangeable between lenses. That said, you might be able to take the working autofocus motor from the free lens and use it to repair the other one. Parts like that are often the same across a large number of lenses.
If you can find a parts diagram for the two lenses, that will tell you somewhat definitively whether they have any parts in common.

That's what I figured. I was hoping some weekend warrior (not in a negative sense) would come out of the woodwork with some crazy 'oh yeah I've done that a million times, here's what to Google for the diagrams' like with some other hobbies. Thanks. Leaving the question open for now to allow other answers.

Sadly, you can't, without taking them apart to find out.
Unfortunately, it's not reliable to assume anything about the construction of photographic equipment.
Even if two instances of what is marketed as the same lens contain optically identical elements, which isn't always guaranteed, you may find that a bevel on the edge of a particular element (or somesuch) is slightly different, because the manufacturer adopted a slightly different way of mounting it in later versions.
You can't rely on repair manuals or other documentation either; you'll often find that the published description is different from the equipment in front of you.
Most typically, you will discover that the manufacturer found a way to do the same things slightly more cheaply.
Having said that, often you will find that the same elements and other parts are re-used across different models, because that too helps reduce costs, so though you get no guarantees, the chances can be good.
