Sadly the new mustangs have a 1 piece dash why you need a new dash kit and they're usually real pricey i haven't seen any done without having to replace the entire dash kit with a new kit. I think they run around 100? but some manufactures do make some really nice ones though that look like stock. Alpines new line up suppose to integrate with new cars not sure if they make it for mustangs yet but i know they did do some for suvs. I would call sonic or crutchfield super friendly and helpful people.
