In 2010 Ford began offering powered tracks and heated seats as options with many interior packages instead of just a few. The 2010-2014 Mustang seats can be swapped directly into the 2005-2009 Mustang without fabrication, however some wiring may be different.
There was a change in the grain of the leather during this generation. We suggest purchasing a matching set of seats and not piecing something together over time as to avoid this issue. Folding rear headrests became available during this generation.
