Took a quick look while I was waiting on an appointment and came across this. Looked to be the most promising, since they show this full console with the organizer detached from the outer shell. Maybe they have the organizer available separately.
Did you have any success in finding this? I have TJ that is missing the tray as well, but I don't have a clue what it even looks like. I was wondering if you had found one, and if you had, could you post a picture of what it looks like?
You weren't kidding they are hard to find. I lucked up on one on Ebay. Not in as good a shape as yours, but serviceable. Thank you for posting what it looked like.
