Are there any specific components that only came on z/28s that never came on ss cars? Besides motor of course. For instance, most 69 zs had 4 leaf spring packs, but they were also available on ss 350 cars right? The same goes for quick ratio manual steering. Many zs had this, but apparently it was also available on the ss cars. Were there any z/28 components other than engine, that were z/28 specific that never crossed over to ss cars?

15 inch wheels
might end up on an SS car if it was ordered with COPO "sports car conversion" but have never heard of one.

[rustbucket29]

Ya I had heard of the 15 inch wheels being z specific. But unfortunately my car doesn't have the original wheels or tire sticker, so I can't use that as proof.

First gen Z's would be 4 speed only with no A/C options. SS could have both or neither as options.

[bilodeaulynn]

Didn't know you were trying to verify a Z.

Does it have a tach, and if so, is it the original?

4 leaf springs are not conclusive, but not common on the SS350.

Original rear?

Original Trans, and if so, does it still have the little ID tag?

Norwood car or LA car?

[camarodude67]

8K Tach only for 69 Z/28 if ordered or May Production car.
Z/28 would be configured with Flat Hood or Cowl Induction.
1969 Z/28 Silver Grill.

Ya this was a generic question because This car has already been in a couple threads. I have gone through all the available numbers and checked every component that is still there. Every piece leans toward z/28, but I have not docs, no motor or trans. And all the components that are z correct were also available on some ss cars. So I was wondering if anyone had any last minute ideas about z specific components. I think I'm just chasing my tail at this point. I just refuse to believe that there is no way to prove what it is. Here is the basic rundown
La car, no x code
Proof of original stripes on cowl panel and spoiler
Two different size spoiler springs
Factory cowl hood stamped 302 holes
Stamped z/28 fender badge holes
Quick ratio manual steering
4 leaf spring pack
Correct BU 12 bolt
Correct disc brakes
Dual exhaust plate on rear frame
Single 3/8 fuel line
Clutch pedal assy
Muncie speedo cable hole
Big bumper guards on rear bumper
Front spoiler
No build sheet under gas tank or rear seat
No motor or trans
No stock wheels
No tire sticker
No radiator
No console car, no tach, read they were an option on zs though
That's pretty much it. So as you can see, it has everything a z should have, nothing it shouldn't, but is missing all the major tell tale parts. So there ya go. The mystery continues.

Thought provoking question.

The later production 8000 rpm tach, sb p/s pump with deep-groove pulley, BO rear axle, AD wheels, throttle rod [male half]. Later cars [June or so] received different engine mounting hardware on the LH side. For ZL2 cars the extension is Z/28 only. When NC8 exhaust was dropped for a short time only Z/28s were built a single-muffler no resonator system. Later on they included resonators. There is a possibility Z/28s received a unique driveshaft.

SS350 did not use the UH radiator but L65s did for certain applications.

If you really want to get technical the steering knuckle, steering arm, rotor, caliper et al was received at the plant as an assembly. "With RPO Z28" is noted in the AIM with different part numbers. I believe the steering parts were shot-peened and had pink paint daubs.

I probably forgot something.

Fifteen inch tire air pressure decal on glovebox door.
Deep groove pulleys on accessories, maybe.
JL8 rear disc brakes.

Have you checked the date of the hood and other sheetmetal to see how they compare to build date of car?
Check here...http://www.camaros.org/numbers.shtml#sheet

What is the casting date of the rear and what is the assembly date stamp? How do they compare to build date of car?

What is the build date of the car?

Unfortunately it will be hard to prove without the engine or at least the block with the partial VIN.

What is the VIN? Have you checked the CRG orphans page?

I thought all SS cars (350 or 396) had Q-Jet carbs which would have a duel fuel line--My LM1 car also had the duel fuel line. I would guess that the single 3/8 line would suggest a Z.

[rustbucket29]

Interesting. I hadn't heard that yet about the fuel line. Is that confirmed that only zs had a single 3/8 line? I knew most ss cars had double but never heard 100%

[bilodeaulynn]

L-78 also had single 3/8 line, but should be able to rule out big block. I think William is correct on the steering parts. Mine had traces of pink paint on the insides of the spindles. I believe the normal disc brake spindles had either a reddish orange or a white daub. Does it have the very very short steering knuckle? There were three possibilities. A Z would only have come with the short ones.

Yes, the tach was an option, but with all the other parts missing, this car could have come with that tach and that could have been removed as well. Look under the fuse block. Is there a 1/2 hole (actually 17/32, but close to half inch? If so, it had a tach from the factory.

So much missing on the car, that it may be academic at this point, but I am sure you would like to know.

[rustbucket29]

I know it probobly doesn't matter at this point, but I really want to know. There are two holes near the fuse block one to the left of the block maybe, 3/8 and then there is a hole looks about 1/2 about 2 or 3 inches below the fuse block. Could that be a tach cable hole?

Tom,

If you have not checked the CRG Visual ID 1969 Model table, there is a lot of information there...
