I like the comparison to the dated glass,nobody seems to question why we buy it and it is accepted in the "game" of restoration. I would object to a vendor passing it off as as NOS and date coded. I see lots of ebay vendors selling NEW parts that are still available through Gm as NOS,items such as brake drums and a body sway bars. "Caveat Emptor" still applies.
I brough two NOS bumpers to a plater a year ago and wa explaining to him that they were NOS. He said they were "rejects" and that is why they were never sold years ago.
