In many cases, the bad ones did go into the new box, BUT then had to be marked and returned to Chrysler for warranty purposes, unless the dealer was "above reproach" and the factory didn't question their warranty claims. If the warranty claim was to be paid, the dealer had to hold the part until the claim was paid, THEN would chunk it as "scrap". If it was a non-warranty part, no protections. If they were bad and "customer pay", why save them? Back then, our cherished cars were just "used cars" and few people saved anything. "Obsolete stock" was either sold to somebody looking for such (that had become non-returnable to Chrysler Parts) and the dealers wanted some money out of it.
In the earlier 1980s, Chrysler (and GM) did "warehouse closeout sales" to dealers. Much-reduced pricing! I bought a box of 100 assorted Mopar fuses for $10.00. '73 B/RB cylinder heads for $30.00 each ('73 vintage, as I recall). 400 cast cranks for $50.00 (or thereabouts). I got a 440MH short block for $300.00. A set of Magnum GT wheels, trim rings, center caps, and screws was $200.00 "over the front counter", so I got 3 sets, picking the best paint for my '80 Newport. A year of so before that, there were confirmed stories of them chunking 426 Hemi short blocks out the 3rd floor windows of the warehouse to "scrap" them out. I guess somebody figured there might be "money" in those old parts?
Just some thoughts,

On ANY NOS part like that, always ask the vendor of the place they got it from. Plus you might ask for pictures of the part and the box, for good measure.
