Sorry, but that VIN will not work with this decoder. Here is the message I keep getting. Just type in Mustang decoder and find another one I guess. You seem to have an invalid "check digit"
"The VIN you entered has an invalid check digit. The check digit is a value encoded into the VIN in order to protect against altering VINs illegally. Since the check digit is invalid the VIN that you entered is not the correct VIN for your car."
