My opinion (may not be the correct one) is that the number you have found inside the heater duct area is not a # that should match up with your body style #. I don't know what that # is (13437Z19) but it looks an awful lot like the same type of # SS427 was referring to that some cars have stampled on the body near the gas tank filler recess. I have seen some of these #'s and they also look much like the number you have listed in the heater duct area on your car.....same number of digits with a letter included. Maybe Rick / Minneapolis can chime in on what his research has shown him about the numbers stamped on the body near the gas tank filler recess.

I don't believe that the fact that the # you have found in the heater duct area does not match the body serial # for this year/model is any indication that the car is not what it has been touted to be.
