Hello, this is my first post here. I had a few recommendations to sign up over here so here I am.

I've had this '70 that has been waiting it's turn for restoration for about 12 years now. Never really put allot of effort into decoding the trim plate, and so I just recently started to think about verifing this car.

I'm going to type this out like it reads...

ST 70 12487 NOR 224691 BDY
TR 711 75 B PNT
03A 28.19

From what I have read now of these trim tags, this is telling me that it's a 1970 8cyl. camaro, built in Norwood, Ohio. Black standard interior, cranberry red, I don't know what the singe B is for, black vinyl top? Built first week of march. Now the next two interest me, because I never heard of any that left out the "Z". But should be Z28 w/black stripes, right? Anybody ever see another that left out the Z?

Would there have been any indication on the trim plate if it had the RS option?

Thanks for your time,
Steve

It looks like you have it decoded right. The 70 trim tags should have just the 28.xx number. In 1971, it changed to Z28.xx

B is for black vinyl top like you thought.

RS doesn't show up on the tag. You have to identify that from the car itself, or from documentation with the car.

Excellent! All of my old literature didn't mention anything about the Z being left out in '70 and it allways made me a bit nervous that it wasn't there. Thanks for the verification! I hope to start a restoration on this car in the next couple years.

Hi, I have a 1970 Z-28 and my trim tag only shows 28.10 so I think it is safe to say yours is truly a Z-28. I imagine some other folks will chime in also. LT1Z28 Cliff K.

OK now I think you guys confused me. I have a 70 z28 also, but my trim tag clearly states "Z28" on it:

ST70 12437 nor305141
711 67 67 pt
06A Z28.10

with a vin of:
124870N554709

I'm 99% sure its a Z28. it has the aluminum spacers under the control arm bushings and the floor mounted pedal too. can anyone tell me this is correct so I can sleep tonight knowing this car I bought 2 months ago is a Z.

I'm by far not an expert on this, but I could make an educated guess. Since I've been told that 71's had the "Z" on the trim plate, and since yours is a late production model, this probably means that at some point towards the end of the '70 model run they started to add it.

I'm sure someone that knows better could add to this.

I'd agree. Nobody really knows when GM changed this stamping on the cowl tag. Like so many things, they might even have done a little of both at the same time. I'd believe either one on the tag if everything else fits.

I have seen both Z28. or 28. on 70 Z28 cars. I dont know if there was a date that it was actually switched from one to the other. I have always read and heard that it could be either way on 70s.

I have seen both also on 70 Z's, so don't worry.

Any truth to the rumor that .28=RS and Z28=STD ? I heard this years ago and often wondered if it was fact or fiction. My `70 Z28/RS has a 03C build and has the .28.10

70 RS Z28

Dan, that's a very interesting theory about 28 vs. Z28. It sounds plausible, as they designated stripe colour on the tag for the Z's, why not RS or not. A consensus of "real Z28" Norwood owners would probably settle the matter. But then again, it could mean something else. There certainly must be a specific reason for the different stampings. - Dale

Well, I'm 99% sure my car was an original RS car, and it's missing the Z.

I think that would be a good one for a poll.

I`ve done a small sampling at various car shows over the years and the theory does seem plausible.The owner of the one RS I saw with a Z28 on the trim tag told me he changed the car to a RS.Remember, this is just a small sample because not many of these 2nd Gen Camaros are at car shows. Its just a theory until proven.

70 RS Z28

My 1970 RS/Z28 has a Norwood 05A build date. My trim plate shows Z28.19. The car is documented by GM of Canada, so I can confirm it is a true RS.

My car is a 1970 2C car and carries the code 28.10. I found the second owner and he told me it is an original RS car. I don't have a POP though. LT1Z28 Cliff K

8 or so years ago, when my Son started his Second Generation Camaro website, we requested that Camaro owners send us the information from their cowl tags. I saved that information, and just went through all the old files. I'm finding 1970 Z28/RS cars listed there with both the 28.xx and the Z28.xx stamps. I have no way to verify any of these cowl tags as I have only the information provided by the owners and I have not actually seen the tags myself.

Gary, within the information you have, is there any breakdown as to options on the cars? I,m thinking that if the difference between "28" and "Z28" is not simply a date cut-off, it means something else. Could it be similar to the "X" codes on '69 Camaros & relating to the style trim group? Or manual vs. auto transmissions? Or??? Again, a consensus of owners of real Z28's would probably shed some light on this subject. Maybe this subject would get more response in the "Original" section? - Dale

No, we didn't get that in depth with the information we collected. All I have is model (Z28, SS, RS, etc), and VINs and cowl tag info to go with them.

If we are to get a definitive answer on this, we might need to get this database as complete as possible so it will answer questions like this.

My 70 Z built 02c,is a "non-rs" and the cowl says .28, not Z.28.

So either it could be done either way, or it was an "early" car deal to have the .28, and a "later" car deal to have the Z.28.
does anyone have a .28 designation on a car built after march? (after 03X)

I have the "option sheet" provided by GM Canada, on the car, which lists all the options,delivery date,destination,etc. etc.

I do not have the broadcast sheet, but I have a collection of several on cd, some I got from Chuck, some from the guy that has a batch at home.

a bunch of the codes for the build sheets are the same between different cars of the same type (ie: z-28's),and some are different.
I have noticed things like different paint code numbers for driveshafts even on same- trans. cars which is weird. ie: Br..Br on one car and Br..Gr on another even though they both were 4 spds.

Different paint markings for M20 vs M21 or M22 or maybe 373 rear vs 410 rear?

possibly, or source codes changed, different brands of u-joints? or who knows.

I think I sent you the info on my car at that site, do you still have it? Just wondering, obviously, I have it, too.

If you sent it to me, I still have it in the files. I can check and see. I'm not totally sure I have cross references to the owners in each file, so I might have a bit of trouble linking it to you at this point. I guess it really doesn't matter because this information isn't available for anybody. We initally said it would be used only for research, and it stays that way forever.

my 1970z28 which came from norwood Z28.10

My 70 Z28 is Norwood built 05B and has Z28.19 on the cowl tag. I also have the POP.

My 70 Z28 03C is Norwood built and has 28.19 and is a non RS car but with the deluxe interior.

so the latest ".28 "designated car so far is third week of march. Intesting. looks as if someone at the factory noticed the glitch after a few months.

</font>I have two 70 Z/28's. One built late May and the other early June. Both cowl tags are stamped Z28. One car is an RS the other a straight bumper car. Have POP for both.

04D Norwood built RS/Z28 HO/white stripes. Tag is 28.10

O.k. now we have a 4th week of april build as the latest .28 designation.

also, apparently owned by a pretty accomplished collector, going by the goody list in your profile........
welcome to the forum, and let me be the first to say...no fair!

I haven't posted on the board in a couple of years. The 70 Z/28 was my first car and I've owned it 25 years. It has a matching number drivetrain, but many many years ago, some people called it a fake because of the 28.10 tag. That was long before the internet and before much was known about tag decoding. It was one hell of a fast car w/the 4.10's for a 17 year old kid in highschool. My dad was not the least bit a car guy. In fact he drove a 71 VW Bug at the time I bought the Z. He about crapped in his pants when I took him for a ride in the Z/28 after I learned to drive it.

The other notable 2nd gen I used to own until a couple of years ago was the Red/white striped 71 Baldwin Motion Camaro that was in all the magazines. In fact, Mad Mike came over one day and went for a ride in it a few years back.

Lately, I've been more into the 69's, but still really like the 70-73 2nd gens.

If you let your kids take the Maro's out, would you consider adoption? lol

The "28" code on Ben's 05D RS/Z28 just threw the theory of the "28" vs. "Z28" being a simple date cut-off out of whack. I have been tracking this, and have a list of 16 cars. There is a 05A & a 05B car, both with the "Z28" designation. I can vouch for the 05A car, as the owner is a close friend, and also a member of this board. Previously, only cars up to, but not including 05A had the "28" designation. Start over? - Dale

Keep it going............

70 RS Z28

Just as a follow up to my Norwood 70Z...it is a 05B build date as stated above but it isn't an RS it's a straight Z28 w/o the RS option. Just thought I would throw that info in there as well.

Anyone else have info on their Z28 to post? Please include as much info as possible, such as: build date,stripe colour,RS?,style trim?,trans.,interior,paint,vinyl top? At first, it seemed to be a date thing, but two cars on my list have contradicted that theory. Need more cars to come to any kind of accurate conclusion, if at all.

I know this isn't the Greatest picture but it reads like this...

You also can see the red oxide through the black which means the trim tag was on when the car was dipped. Almost forgot, Bumper car Non RS
