Depends..Can the repop guys get crisp lines as original? I would prefer NOS on lens. During a conversation with a gent (a trim guy) who worked on the assembly line in the 60s-70s he said any parts with a flaw went over to the ‘NOS’ box. Also said if the right part was not in the tray, what was available on the tray went on the car. Case in point my 66 Belvedere II came off the assembly line with Belvedere I lenses, no chrome pieces, it’s going back the way it came. My NOS lens look perfect.
