If you have backup cam, you will need to consider purchasing the Ford emblem (for 2013+) which incorporates the cam into the emblem.
Or choose to do w/o rear view cam entirely.
The spoiler will fit, but it won't be a "simple" mod as desired due to different design & different mounting points.
You can do body work to fill holes and repaint, but keep in mind the aforementioned back up cam issue.
Additionally, if you chose to purchase a 2013+ trunk lid (in theory to make it "easier") you might also consider going full tilt & picking up a full set of the LED tails & complete the look.
