There is some inconsistencies between the 2013, 2014, and 2015 models with regards to logic board compatibility. Find your serial number and put it into the parts checker on powerbookmedic to be sure. I was in a similar boat and had to double and triple check which logic boards were compatible before I bought one. Powerbookmedic will give you specific parts numbers which you can search on ebay and elsewhere for replacements.
