911 1974-89 floorpan, right side. Galvanized primed painted. One of the most abused part of the 911 are the floor panels. Years of exposure to moisture, salt, sand, and mud often takes a toll on the metal under your feel. If your Porsche floors have seen better days and are showing the ugly signs of corrosion, we have replacement panels. Each one is painstakingly made to duplicate the factory pieces and galvanized for long life.
