"Under the center console cover." Are you talking *inside* the center console? I don't believe I've heard of anyone talking about adding a tray inside there. However, if you remember the manufacturer of the tray in your T&C, you can try their website to see if they have an Odyssey version. Or, try googling it.
One thing worth doing, since it's so cheap, is to use various sized zippy bags. Ziplock, Gladlock, etc. Keeps like things together and is easy to rummage around to find what you're looking for.
Yes, I'm talking about inside the console cover. The T&C came with the tray. It was about an inch and a half deep and held items you used on a regular basis. Organizing the well area with baggies is a good idea. I just don't want to rumage around in there too often. I'll keep looking. If I find something I'll post.
