I believe these breaker plates being sold by Ebay member "mysunshine302" are NOT NOS.
I purchased one a couple of years ago, and upon inspection, the breaker plate looks brand new. It looks as if it has been media blasted vs what I would expect a NOS finish to look like, smooth with some patina.
Also, the seller didn't want to give up the original packaging, which is a bad sign, but he had inadvertently stated it in the ad, so I got it.
In this ad, the seller is selling the plates and what looks like a photocopy of an original Motorcraft instruction sheet. He notes that the original packaging, which is hard to reproduce, is not included.
I could be wrong, but certainly seems like these are reproductions. Just be aware if anyone decides to buy one....
