If you have relocated your coolant reservoir tank to the rear of the car, this is the panel you need to close that space out.  Fits and attaches in the same locations as the FFR provided panel with the addition of another mounting tab on the RH side of the car to duplicate the LH mounting tab.  Made from .040″ 6061 Aluminum (same as the panel it replaces)  Notice – This item ships flat (as shown) and you are responsible for making the necessary bends in the panel.  This keeps the price of both the panel and shipping down considerably.
