I found GM part number 84106530 for center console tray, for my LTZ with front bucket seats:

It is $60 plus tax which is ridiculous price for a piece of plastic. Previous model years had the same tray with different part number 22817343, and you can find them in very cheap prices. When I checked the dimensions, it looks like that the old one can fit in the 19 consoles.
Has anyone had any information about these trays?
