Thank goodness the adds at Craigslist are free!!!!

Wow, he is on some pretty strong s**t!!!!

after inhaling nos everything is nos

New never installed.......O but it did sit out back behind the barn for 30 years lol

Everyone in the Pittsburgh area thinks they have a gold mine in their old car parts, and their old cars (except for me of course) :D

NOS-nasty old s**t

I'm not surprised.:)

Like I have said many times in the past. Crack doesnt smoke itself.

Could easily be NOS. And I think it is.
Has obviously been subjected to some moisture over the years.
But I suspect that the rust you see is merely surface and will blast right off to reveal a smooth new surface.

fwiw, these parts only come from GM with a black protective paint on them. It is not designed to be used with this coating. Should be stripped and properly prepped and painted.

The only reason you see black paint on GM sheet metal is to protect it from rusting before it gets to the customer, which can be many years after it is made.
It's not uncommon for a part ike this to have substantial surface rust. I found a 70-72 Nova RF fender at a garage sale about 1997 that had been hanging on the wall of a carport. It has rust very similar to this core support. The part number tag was still there, but as soon as I touched it, it fell off. And it was faded quite a bit.

Been that way for years, it seems. I stopped going to Butler Parts-A-Rama long before I moved to Central PA, because it seemed like all the parts there carried insane price tags, or weren't even good enough for the junk pile.

I'm with MR69. The part is over 40 years old, for God's sake. Surface rust for something that old is not unusual, no matter how it was stored. Too many people think that NOS parts have to be in pristine condition to be truly New Old Stock. New Old Stock in the truest sense of the word means an original part that has never been used. Not an original part that has been stored in a climate controlled vault.

And you would pay $500 for a rusted core support? That part would have to be in perfect shape for me even to consider it. Even then, I'd have to think again. I put a $100 repo in my Nova and it fit perfectly and was stamped just like the original. With the grill, hoodlatch, radiator,ect, installed, you hardly even see any of it.

I totaly agree, I have two rusty core suports I got off of cars and i still went new repop, fit great no sandblasting and painting needed.

Try reading my reply again before you jump to conclusions. I never said a thing about the price and whether or not it was worth it. I merely commented on the fact that the general condition of the piece did not preclude it from truly being NOS.

I have had plenty of nos parts that had some surface rust on them and still sold for some big money.

I have two full quarter panels for a 70 El Camino ( The boxes are 9-10 long and 5 Ft. tall ) in my basement that I bought from Kenny Ross Chevrolet in 1981. They are in the Black & Yellow boxes and they may have some surface rust.
I would guess they may be better than a Repop.

OK, its truly NOS. And, its truly crusty as hell. And most people would truly expect better than that, if it's NOS. The point of buying/paying big $$ for NOS is to avoid repops, or refurishing old original parts. And thats exactly what that part needs. So whats the use to advertise it NOS? Maybe he meant Needs Obvious Sandblasting :)

Kinda hard to tell from the photos if it really is crusty as hell or just surface rust - but that's neither here nor there.

The purpose of advertising this piece or any legitimate piece as NOS should be obvious to you. For some high-end restorers, there's magic in those words. Condition notwithstanding, there are people who value original parts over reproduction pieces and are willing to pay ridiculously outrageous prices for them. Regardless of your personal opinion on the condition of the piece, the seller is going to attract a lot more interest advertising it the way he did. Will he get his asking price? Who knows? There's guys who will do it, no matter what their motivation. Not much different than the stupid prices that some cars bring at B-J auctions.

But if you look at the original question, the poster simply asked if the piece looked like it was NOS. Not what you thought of the condition. Not if you thought it is worth the asking price. Simply, do you think if it is an original, unused part.

Well nos dose mean NEW condition as far as im concerned and most people relate the term NOS to top dollar and thats why everyone and their mother who is selling parts list them as nos!
That being said if someone had an nos fender stored in doors all its life with minimal and i mean minimal if any rust on it, it will hold its value but if you grab some pile of sh%* from out behind a barn and it has the gm tag on it and no bolt/screw marks from being used but is a pile of crap rusted and probably distorted etc,, is it worth the same as the other just cause its NOS!!?? seriously!!

I am the poster. Seems you like to disect my post. Sorry that you cant comprehend what I'm asking, but, "Looking NOS" means, not looking like that . And you know people dont expect to see something like that when they click on an NOS listed item. And I'd bet most of everyone who clicked on my link, gaspped when they saw it. Because they expected something in new or better condition.
Why not build a car with all NOS parts that are in that condition, and try to sell it for $100k, and see what you can get for it . $0. But hey, its all NOS. The parts are unused ! Thats all that matters, right?

NOS parts can have rust.
And a lot of them do.
I don't see what the big problem is here.
If you need it, you buy it and you blast it and you prime it and you paint it and it's going to be far better than any repro and probably better than 90% of the orig ones you'd find today.
Terry, I think you have a lot to learn.

The black coating that is on new sheet metal is called an e coat.
It is only there to prevent severe rust before the customer gets the part.
Furthermore, it should be stripped off and properly prepped.

When you buy an NOS metal part, it doesn't come from GM ready to put on your car.

And you know people dont expect to see something like that when they click on an NOS listed item. And I'd bet most of everyone who clicked on my link, gaspped when they saw it.

Those of us that have been doing this longer than you know that the rust seen on this part is absolutely no big deal.

In fact I will go further than that.
I like to see the rust on this core support.
Because unless it was stored in a climate controlled environment all of it's life, I would expect to see surface rust like this.

The rust I see doesn't scare me one bit. In fact I like it. because I know the part hasn't been blasted and painted to hide something.
