There's many instances online where a NOS GM part is shown for a reproduction being sold. Many would never know, just the stock photo used. Found it several times comparing them for the NOS vs Repro thread. So often the details simply don't match what is supplied. The body door jamb vent is a common example. There's a few unique moulding details that only feature on the GM, but more obvious is the recessed screw hole that nearly every pic features but is yet to be seen in a repro.
