If you dont mind losing some additional space in its drawer, install the mirror on flat wood and fix this flat wood piece onto drawer slides which are fixed onto the hinged cover. If allowed to post hardware only for - amazon has these 4" ones small enough. And add a few peg holes vertically in the middle of the lid so u can make it sorta adjustable as well to multiple in between max open and max close heights as needed.
