Not exactly - NOS is "New Old Stock", which are supposed to be identical in every respect to what was actually used in production, and were made during the time the car was in production; very rarely found anywhere, as most service parts were slightly different and were made after the car was out of production. What you find 99% of the time in original GM packaging is NORS, "New Old Replacement Stock", which are service replacements; they are "functionally equivalent", sometimes made from the original tooling, but not necessarily identical in appearance to the original production part (which is why they carry different part numbers in the GM system than the original production part number shown in the A.I.M.).
The sill plates currently available from GM are "NORS" - they fit fine and look pretty close, but the Fisher Coach emblem isn't riveted on. 99% of the stuff you see on eBay advertised as "NOS" is actually "NORS" ("functional equivalent" service parts, not original production parts) - you have to know exactly what you're looking for. Sellers stick the "NOS" description on everything, hoping to hose as many people as possible.
In some cases, good reproduction parts can be closer in appearance to the original production parts than current GM service replacement parts in GM wrappers, depending on how (and by whom) the GM service parts were made. GM doesn't make our old service parts - they contract that business to outside suppliers, who may or may not have access to any of the original part's tooling (if it still exists and it's worth refurbishing to work in the supplier's equipment).
