Brand new production.. and thankfully this is available as many people over the year have spent too much trying to restored rusted and damaged rear panels only to have them fall apart again.
This is the 1967 panel as the way GM made.. as shown.
CHOOSE from 1966 (top image below) or 1967 Panels (Lower image below).. as they are different (66 &67 different.. and shown bigger images)
