I was looking everywhere to see if anyone has swapped mirrors from a 2004/2014. Well I didn't find anyone to do it yet. I bought a set for my 06 FX4 an they do fit . I swapped them off a 2014 F150 an they function perfectly. Electric mirrors, they had the same connection plug. Just in case someone else was needing to know. An they are cheaper than buying my stock mirrors.
