I think you sent this to the wrong person Tour...
Nope. Look at his pics a little closer.

They look very similar to the GTO kit you could buy through gm parts once upon a time:

They’re not a GM parts, they're aftermarket.

They were only sold through GM parts.

Pretty rare pieces and hard to find these days...

Nope, my car has the Greenwood kit:

Mine has a “real” Greenwood kit, not a copy. 9 times out of 10, the copy kits are easy to spot. The Greenwood rear spoiler has “Greenwood” embossed on the outer wing edges and the mounting pillars have two outside ones and one in the center. Even the knock off ones that try to get past muster by embossing Greenwood on the outside edges always seem to only have two mounts instead of the Greenwood three mounts:

As opposed to:

Greenwood DID make a spoiler with two pillars, but theres no mistaking that one for anything else:

That was for one of his “special projects” and they called it the C4R IIRC. Thats just a bit too “over the top” for my liking...

Mine has the “short” rear pieces instead of the Greenwood full rear pan. Greenwood stuff could be bought individually, so customers could mix and match the bits. Whoever bought mine in its past, decided they didn’t want the full rear “aero-pan”. They made the right choice IMHO.

Truth is: I’d be just as happy (or happier) if my car didn’t have that stuff on it at all. But I’m stuck with it as there’s mounting holes on nearly every piece and the car has been re-sprayed at least once with the body kit in place. So I can’t take it off without doing an “s-load” of body work and a full repaint. Thats just not in my budget right now....

Greenwood knock offs are fairly common to find these days, mostly because they were one of the most popular kits (and some say the best looking) back then. But a “real” set of Greenwood ‘glass is almost as rare as the GM GTO stuff. GTO (and Greenwood) stuff is out of production and has been for a long time. Note that “rare” doesn’t necessarily mean “valuable”...

So, different spoiler, different nose, different sides and tail.

That is definitely the “GM parts” rear spoiler on his (or its a VERY close knock off) and the front is different from the Greenwood in both shape and execution.

The Greenwood front has wider end pieces, the center section is recessed and theres a “support strut” right in the center of the Greenwood kit to help prevent sag. Theres also a “lip” on the GTO front that the Greenwood does not have.

The GM parts kit could be bought by anyone, but (supposedly) it was intended to clean up the aero for track use.

Nearly impossible to find those parts these days. Even running across a used set is nearly impossible...

you mentioning having the parts pretty much "fossilized" to the body via paint remnds me of the hangars on the 280 class ships. as you know, they were designed to shear off in sea state 5 type of seas, so the hangar wouldnt fill with water and capsized the vessel. i remember so much paint they were glued almost lol.
 
The kit was originally from the GM parts bin. The interesting thing is the Corvette body shop that was going to install the aero kit was not impressed with the quality of the product, they had ordered the kit for me. What they did was make molds of the kit and actually manufactured a much higher quality product. They made a total of four sets- one for me, one for the owner of the shop, one for the son of one of Duecks owners and one for the shop as an advertisement piece. I always loved the look of Greenwood's kits. I promised myself if I ever won the lottery I would go looking for an original Greenwood 1981 GTO. There were only 2 built, but I remember seeing one at Mecum's Florida auction a few years ago, and it was a no sale at $40.000 USD.
 
1984 here in Quebec , Canada. Wish the first year C4’s got more respect ,after all they set the stage for the Corvette for every year after.
The technology, the handling, and the curves are still modern today.
