A PO filled the antenna hole in the RF fender and installed a remote antenna (somewhere in the car). I decided to go back to a stock antenna picked up a Fiero antenna with the mounting bracket that bolts to the body inside the fender, but I don't have the bezel that fits into the hole in the fender. I never had this part so I assume that it just locks or is held into place on the fender? Anyone got an extra?
