trying to decode my 69 rs z28

[DarrenX33]

Cars that didn't have trim tag X codes like early Norwood cars and VN cars usually always have this marking. The theory is that someone marked it there to let the line workers know what the car is when it goes down the line. I have seen a combination of X and then the single number 1-7 (X11,X22,X33 and etc) to identify the car. I have also seen where the X is omitted and the color was abbreviated. For instance Sam's Z has DG3. His car is a style trim Z that is Fathom Green (DG = Dark Green). I also have a picture of markings in the same spot on a base car that is Garnet Red. Care to guess what the marking is? Yep. R1.

Kris' car is Fathom Green that is why I suspected that there could be a DG in there somewhere. But in his case the worker put X3.

Markings have shown up on the firewall. We just had a thread where after mediablasting all the codes were revealed. Here!

These hints on the X codes are obviously unique to 69 Camaros. I am not sure what might be there for 68s.
