I'm looking for the alloy trim/surround piece that goes around the rear window for a Fiat Abarth 750 Sedan (Berlina), also found on some of the Fiat 600 Sedan cars that were fancied-up by various Italian coachbuilders back in the late 1950's (Canta, Siata, Moretti, Viotti, etc.). This is the alloy trim around the main rear window (above the engine lid), not the trim on the rear 1/4-windows.
