As stated earlier the car was modified at some point in it's life for air conditioning. Typically the Porsche factory "preped" the cars before leaving Stutgart but it was up to the local dealers to install the actual equipment. Well if this car is any indication of the caliber of work done to install the air I'd have run from every dealer I came into contact with! Seriously. The car was "hacked" with no regard for rust protection, body strength or anything. We took it upon ourself to do this repair the right way the way the factory would do it had they been restoring the car.
