Looks like you need replacement
·DISPLAY PANEL BRACKET(S)
Most often sold as a pair (1 left /1 right).
However, I have seen brackets sold individually but usaully harder to find that way.
· TOP COVER
Most often sold w/o hinges
However, you might get lucky and find a cover w/ hinges.
Sold in pairs. (1 left/ 1 right)
I recommend replacing them as a pair. (These hinges are the reason for all the damage. Hinges get too tight (even seize up completely) putting stress on and causing the metal display brackets and plastic parts to brake).
