This car has original window sticker (laminated) and build sheet with 9796 COPO on both. I am told it has all original motor tranny, everything from carb to rearend is original interior untouched, all metal is orginal. Was wondering if anyone could give me some help on decoding it when I get there. I am also wondering if anyone knows where to find a picture of a original window sticker of a 1970 1/2 z/28 with the copo code on it or a build sheet w/ the 9796 code on it. any advise would be great too. thanks

thanks, anything specific to the copo?

Are you talking about 2 different cars? Copo Camaros were done in the 1969 model year. No such thing as a Z/28 COPO, that I am aware of. This post will get some attention from the real experts I think. For sure get some pictures and try to post them.

1970 1/2 there is a copo Z28 that was the begining of the 3 peice tall spoiler and front spoiler avilable under option code (copo 9796) begining in late april of 1970 aprox 500 made claimed by gm to satisfy SCCA racing regulation but it is suspected alot less were made and the only way to prove it is a true copo as far as I know is with the build sheet or window sticker.

Interesting.

Yea its just a spoiler thing.

So the one-piece rear spoiler was standard? Took a COPO to get a 3-piece spoiler?

I believe the COPO 9796 would not be on the invoice but it is on the buildsheet for certain.

The place to find out everything you ever wanted to know about 70 COPO's and 10x more than you'll need to know is www.nastyz28.com. Post your question in the original drivetrain section.

You might also ask your question on the www.yenko.net site. Quite a few of those guys either have these cars or know extensive info about them.

A couple of threads that will interest you: Both contain tips on id'ing a real COPO spoiler car.

Mikala, post at www.nastyz28.com They will know.

I thought both spoilers were options. No COPOs, at least in the 1st gen sense of the 'word'.

for 1970, the one piece spoiler was standard, all cars ordered with a spoiler got them.

As stated earlier, there was the start of the 3 piece spoiler availability and it WAS an OPTION, but it took a COPO order to get one ... and it included the front spoiler as well

Starting in 1971 the one piece spoiler was STANDARD (as it was in 70) on the Z28 and the RPO D80 3 piece spoiler was optional and included the front spoiler

rare original paint 70 z28 with COPO spoiler package and stripe delete:

Thanks Jim, didn't realize hoops were needed to be jumped through to get that.

Just keep in mind that cop cars, taxi cabs and almost anything fleet was COPO ordered. The fact that in '69 they used the COPO for performance options is why the name COPO sticks and has meaning. I really like the 3 piece spoiler and Jim's example is a really sweat one. It's cool trivia to know the spoiler was acquired through the COPO process but the spoiler was just a bolt an option that wasn't on the order form.

I would hate to see a spoiler put a 1970 300hp 350 into the same ranks with a '69 ZL1 or other factory 427 car because they are both COPO's...

The Larger 3 Piece Rear Spoiler and Chin Spoiler was introduced by GM in approximately March 70 to make the Camaro more competitive under TransAM Rules. Any Model of Camaro after that date could be ordered with this Spoiler Option. Previous Camaros owners could simply go to the GM Dealer and order the new Spoilers and bolt them on. Other then having the original built sheet as an indication to whether the car came from the factory with this so called COPO Option is to check the Rear Fender Spoiler mounting Holes. If they are not perfectly round and neat the COPO Spoiler was probably ordered from a Dealer and bolted on. I'm the 2nd owner of this 70Z and have know the car since 71 and it always had the COPO Spoilers. Because the Holes in the rear quarters are not perfect I suspect they where Dealer Items. Whether the car can be considered COPO is a matter of individuality in my opinion - LOL

Here's a PIC of the car today:







The Grill is large egg crate 71 and in my opinion stronger and looks better then the 70 grill. I still have the original. NOTE the Hide-away Wiper Option. Other Options were White Stripes, Sport Mirrors, Instrument Cluster, Floor Console, M21 and 4.10:1 12 Bolt Posi which is very rare. In 75 I was fascinated with Baldwin Motion and sold the 350 LT1 and put in a 454 out of a 73 Laguna El Camino. Over the years the 454 has been bored .030" Forged rotating assembly, oversize Manley Valves Jomar Girdle, Mechanical Roller, Donovan Gear Drive ... etc etc producing approx 620 Hp @ 6000rpm and 637 ftlbs of torque at 4500rpm and thats on pump gas without NOS. A fire extinguisher resides in place of the cheap floor console and Connley Leathers from a BMW replaced the original and uncomfortable Buckets. The Original Rims just could not take the power so I replaced them with Vette Rally 15 X 8 on front, 15 X 10 on the Rear and run BF COMP T/A's. Steel rims are strong and much cheaper then dangerous after market rims that break if you have to jump a curb. The Old School Flares on the rear quarter keeps the car Legal as rubber can not extend beyond the skin of the car.

The COPO thing of any year does not intimidate me ))

By the way, I notice like my car the "CAMARO made by Chevrolet" Badge is missing on the trunk lid of that elegant 70Z COPO. Mine is in the glove box just never got around mounting it after paint.

In my opinion the 70Z and BB/SS Camaros are the Ultimate Muscle Car as it is the accumulated product of years of GM Performance Engineering with a Shell Designed Specifically for Racing. Ist Gen owners must envy us because there simply is little to modify or fix to make this car a Winner.
