and that is what i have...from his sig he has a 2011...so in order for a 13/14 decklid panel to fit a 2010-2012, the back clips on the 13/14 decklids panels need to be cut off and sanded down and then stuck onto the trunks. that is what has been done to my 13/14 decklid panel that i bought a month ago. that is why i told him to pm me with an email so the pictures can speak for themselves...
note** this decklid panel was a takeoff from a 13/14. i bought and prepped it for install, however im trading my car in sometime next year for the 15 or 16 mustang so i want to sell this instead of installing it.
