Search up the Mac's serial number located under the bottom of the Mac which is near where the a1398 label is located.
A1398 tells us that it is a MacBook Pro Retina 15” model. The problem is that even if the screens are identical they are not compatible with different year / mid-late-early models unless specified otherwise.

That will give you the exact model of the MacBook which you can search based off of to find compatible replacement parts.
