Hopefully this will help -
Please see the attached pics - I dredged the bezels out of storage this morning. Standard bezels carry a different part number on the box than the chrome ring bezels, but all three have the same casting numbers on the reverse (see all three pics of the part numbers). I have pristine (uncleaned, unrestored) R&L black bezels, chrome ring, for my L78 Cortez 12A SS - plus NOS chromed Argent, and Argent/not chromed bezels for the X77. Unfortunately, the black ones are used, but definitely gonna go back on the car.
Regards -
