Yes, possible.

I think the three piece spoiler was later production, possibly an option. When I bought my 70 1/2 (first one in town), the spoiler was one piece. TAZ

Unless you have a build sheet saying 9676 or the car can be certified as an undisturbed original paint car, the high spoiler could have been added at any time over the car's life. The spoiler existed because of the car below - it had to be homologated for the 1970 Chaparrel Z28 Trans-Am cars, which meant offering it as a factory-installed option.

The high spoiler carried on as an option in 1971 and 1972, you had to order it as D80. Further, in 1972 if you didn't specifically order your Z with D80 you got no spoilers at all. Ever see a bare-back '72 Z28? It's weird. Looks like a shaved cat. They used one in the ad below...

That is a 1971 Z (notice the high back bucket seats) and if I'm not mistaken, the three pc spoiler was standard in '71...

If it's a Van Nuys built Camaro, there is a very good chance it is on top of the gas tank. If Norwood built, highly unlikely you will find one.

I think you mis-read my post or didn't read it completely...I posted the ad for the <span style="font-weight: bold"><span style="color: #FF6666">1972</span></span> Z28 to illustrate my post about NO SPOILERS ON A '72, unless you ordered D80. And, no, the high back 3-piece spoiler was most certainly not standard in '71. You had to order D80 to get it.

Hi Des, I did not see your initial post but clear now and agreed. When I say standard I was inferring to when you ordered spoilers you got the 3 pc unit but the 1 pc unit. Isn't the ad for the Red Camaro a 1971? A '72 would have a different grill unless this is a fault of Chevy's poor timing in advertising...

It's from the 1972 Camaro brochure. When it's an RS-optioned car, the grills are the same 1970-73.

Des, never once realized the RS grill was the same throughout. This whole time I was focused on non-RS front end. Learned something new (despite seeing it 100 times prior). Great stuff.

Subject Vin is approx' an 02B build which is about two months too early to be a 9796 car.
Sorry and someone wiser can clarify but I believe 9796 was first available mid April '70 and on?

Hi, I PM'd the original poster. I'm the current owner of the car. I had it dropped off last night from Portland, Oregon. Car is not in the best shape these days. I've connected with COPO, Joey Gray in NC and others on the car in question. It's a 02B-ish car, no cowl tag or any documentation. A few follow-up questions prior to hopefully hearing back from "70 LS6 Convert".

- From the factory vs. an install at some other point, how was the 3-piece spoiler attached?
- Since the tall spoiler became an option late April and this is a February car, "if" it came factory-installed, wouldn't that make it a COPO car?

Here is a post I had on the NastyZ28 site.

http://nastyz28.com/threads/1970-la-z28-copo.321191/

Additionally, the car looks like it was a black with stripe repaint of an original green mist car based on the color I saw from the interior.

Thanks for any additional information.

70 copo 09-17-2018 10:08 AM

The Spoiler is installed the same way. the quarters and the trunk are drilled and elongated sufficient to align the spoiler caps to the center. The early AO Smith end caps were junk and a miss alignment of nearly an inch was common at the tips so shimming is required to get it close. Too much and you gain gap in other places...

If it is an 02B car, the spoiler did not come from the factory.

Mr.Nickey Nova 09-17-2018 02:25 PM

Take a look on the bottom of the truck lid for the mounting holes. See if there any other holes present. If so, then the COPO spoiler was added. The holes are different for the short spoiler compared to the COPO. A buddy of mine had a 70 Z with the COPO spoiler added, but originally came with the short spoiler. You can see clearly the mounting holes from the short or one peace spoiler.

BCreekDave 09-17-2018 02:48 PM

If you look at the NastyZ link the OP sent there are some photos showing the lid has several extra holes that go to the short spoiler.

Not to mention that car is so bad even if it was an original COPO it wouldn't be worth resurrecting it. George Washington's ax!

That's the tightest fitting back bumper I've ever seen on a second gen.
