My x33 non RS Z

Frankly, I know nothing about "build sequence production" vs whatever else kind of production is being touted; and I really don't care to get sucked into whatever argument or ongoing debate there might be.

Clearly, we now have three fender extensions with markings that certainly don't APPEAR to be numerical. I don't think you can interpret that 2nd one as 612 or Bill's as 6111. That certainly does NOT in any way indicate that there wasn't build sequence production." Just means that for some reason a worker put some code under there.

All three have a G, so that would lead credence to the theory that it had something to do with emblem choice, as all three are Z/28 cars. Damn, both my fender extensions had small creases, and i replaced them both when I painted the car (also a Norwood Z/28). Makes me wish I had looked at them very closely before getting rid of them. They were original to the car. The fact that several have surfaced with "COPO" scrawled on the inside also supports that theory (no front emblem).

The R also makes sense as Rally Sport, as that RS emblem is virtually impossible to install once the front clip is on the car, as is the Camaro emblem.

So, what in the world would the "M" be there for on Bill's car?

Doesn't Lloyd (Edgemontvillage) have a survivor RS 69 Z?

How about taking a look?

One 69 COPO I restored had ...."427M."...on the extension, picture has been posted before. Still can't figure out the meaning of the M.
And I agree with the 126 theory JMO

Just found this

This is a late 1969 X33 fender...Joe

So with the data we have G = Z28 R = Rally Sport and M= Style trim without/RS


Obviously this is a very small sampling and much more data is needed so lets see where the data points take us. So far we only have data for COPO and Z28 .


We should set up a spreadsheet and include SS396, SS350, base model. Or how about COPO, x11, x22,x33,x44,x55,x66,x77 . Just a thought so the data is organized....

Pics I took of the low mile RS Zl1

Called another Retiree this morning. His read was as follows. Sequencing # was used but was dependent on who was working the station. His recollection was under the upper valance for the number.

His take on what he is seeing here:

RG= Rally Group

GM= General Match

427M = Match to 427 doghouse assembly.

Likely also 350/396M and RG used there as applicable as well.

The piercing codes either start with X or Y, e.g. XC.
While the COPO cars often have 427 in this location, I don't recall seeing a piercing code here, fwiw.
I have seen three letters written here, G, M, and R (and 427).
The G was a Z28. M has been non-RS. R has been RS. G & M have been exclusive of each other. Don't have any notes on SS cars.
