I recently purchased a 2012 unibody and 2012 display and put a late 2011 logic board in it. The only thing that didn't line up was the heat sink. But everything else worked fine. I'm not sure if you were going from a 2011 unibody to a 2012 board. The lcd cable will fit fine either way yet I'm sure you will not have the high resolution with a 2011 display.
