Hi, I am searching for the top case (alloy-part where the display sits) for a MB pro 15” 2017 space grey. Do you have one?
I gather you have a dented lid on your system. Sadly, the case part is not available as a spare from Apple. In addition the display is very difficult to disassemble without breaking it. Even the older retina models are hard to open without damaging them as you can see here: MacBook Pro Retina Display Teardown So what to do?? If the display its self is working I would just get a case cover to cover up the damage. If its scratches then a skin could be used. If the damage interferes with the lid closing or the screen is also damaged then its time for a replacement lid assembly MacBook Pro 15" Retina (Late 2016-2017) Display Assembly would be the easiest way to fix things.
