The exterior dimensions of both headlights (10-12 vs. 13-14) are the same. What's different are the internals and one mounting tab. The 10-12 headlights have a tab on the top that stands up and is used to mount part of the bumper. The 13-14 headlights do not have this tab. But you can still use the 13-14 headlights by coming up with a different way to support that part of the bumper, such as this:
The cut piece of metal is taking the place of the missing mounting tab in that picture.
I imagine the connectors and ballasts would need to be transferred over as well, but I can't say that with certainty.
