Box 104 on the BBC is for the fender emblem.

Very limited data indicates C for 307, E for 396, F for 350, G for Z/28, H for 327. Wonder why COPOs had 427 written there as they would have the same piercing and no engine ID emblem as the base 230" six cylinder.

Also, COPOs and Z/28s [non RS] have the same YA piercing code. Non HP cars are XA.

The scribbling on the extension may be tribal knowledge.

Here's another. This was a true SS with style trim w/o R/S. Fender run number 37. I don't know the engine size. Fender is damaged there...Joe

From this photo in the CRG assembly process article, the buck-built front end was assembled with much of the grille components and headlights, so the build configuration including paint color, any striping, std or RS grille and headlights and hood style would be significant during that sub-assembly, as well as the fender piercing already discussed.
The ident number can be seen on the driver side of the firewall, so a corresponding number on the front end seems logical.

Thanks Mike, I saved those pictures a while ago but lost my notes on their source. Was it a non-RS car, and if so, did it have style trim?

FYI this is not just on 69’s. Have a few 68’s with R6. I originally thought it was for 396 RS but that is out the window.

If no one else has a spreadsheet going I’ll look for mine in the am.

My memory is failing me. It’s 6S and this was from a 68 SS/RS 396 convertible.

Thanks Bill! I got caught up in looking for fender extension pictures that I forgot this.
C - 307/327
D - L22 L6
E - 396
F - 350
G - Z28
H - 327 (no idea why this car isn't C)

And:
M - Z21
R - RS/Z22

And there's your 69 decoding ring.
