I currently have both of the macs above, but one has a broken display. Both screen assemblies look identical, but are they able to be swapped out with the other? Update (04/25/2017) The EMC numbers (if helpful) are 2881 and 2909 respectively.

Sadly, The parts are different: MacBook Pro 15" Retina (Late 2013/Mid 2014) Display Assembly - Apple P/N 661-8310MacBook Pro 15" Retina (Mid 2015) Display Assembly - Apple P/N 661-02532 Besides don’t you want to have two working systems?
