Review this guide [guide|536] Open up each part to see which system is supported. To find out what your system is exactly plug in the systems serial number into here [https://everymac.com/ultimate-mac-lookup/|EveryMac - Lookup]. This is the best way to see if they are the same display assembly. Do keep in mind your system uses CCFL’s so an older display will likely have a dimmer display as the tubes loose their brightness overtime (use). This would be true with any used part.
