I think they did such a good job designing these (and all manufacturers do this - Sequoia or Tundra, Chrysler Town & Country or the Sierra minivan or Honda Odyssey...) to be swapped out so they only use one framework and the pieces just swap out depending on what they're building - but that's on a PLATFORM to PLATFORM basis, and it might not carry over from the Trucks to the SUVs (although it might!).
There are some exceptions like the flip-down DVD players that you see in the latest Sienna for example, but otherwise you should just be able to call up your local Toyota Dealer and get them to check the part number. If it's the same part number for the Sequoia and also for the Tundra ... then it's a direct swap.
Other than that, you'll just have to find one that you can look at (car lot, or a wrecking yard) and get the dimensions. Just note that a boneyard will sell you the whole thing, not just the console door.
