And, as the rsgear (Richmond Standard Gear) guys are in the business of
selling replacement parts for these, it seems they have a strongly vested
interest in discovering the variations, and getting the shops that call them
for parts to tell them what they really need to know.
Calling up and ordering "gears for an NV233" isn't going to get very far. One
of his tech articles basically says that before you call to order parts,
you'd best disassemble the unit you're working on, measure each part, write
down every part number you can find, and count the teeth on each and every
gear and write that down too. Because otherwise you're just wasting his and
your time, since he won't know what to sell you and you won't know what you
need to buy.
I enjoyed reading a bunch of his stuff.

I agree, but it seems unlikely to happen. And, at the junkyard level, isn't
that the point of the Hollander interchange list?

I used to believe that at least if I went to the dealer parts counter, told
them what part I needed ("NV233 transfer case") and for what ("2001 Dakota,
V6, manual trans"), that I'd have at least some hope of getting the right
part. Given my experience with just trying to get O2 sensors, I no longer
think this is likely.

For straight service replacement, it should exist. I don't know if it does.
For retrofit and other modifications, though, you're pretty much on your own
to figure it out.
