As I view it, technically, if it was a Moog part they no longer made but was still a new part, it could be considered new old stock, or NOS. "NOS" doesn't always have to mean factory replacement parts, like GM in our situation. Although, it's been canon from eons ago if somone says "NOS G-body steering part", it was assumed it was a new, obsolete, GM part. Sometimes people claim a part as NOS when, in fact, the part is still available from the GM dealerships. Then, it's just considered a "new" GM part, NOT an NOS part. But sellers aren't always fluent in car parts so they often figure if it's new, and old, regardless of what it is, it's deemed "NOS". Which isn't always true.Some eBay sellers also list aftermarket parts as nos. Years ago, I told a seller on eBay that his his new Moog tie rods were not nos. He replied that they were nos, just not oem. To me and most car guys, nos has to be from the original manufacturer.
But when a part is clearly USED, and they use NOS in the description, then they're just lying. Used is used, and new is new. Could qualify for UOS, or used old stock. 🙂
Just be careful of the terms that sellers throw around.
Here's another one I find problematic. Anyone think this is NOS? Look at it. It may work, but it's certainly not all brandy new.
