I think the data points collected so far correlate with the broadcast coding information. I'm encouraged, and want to keep the data and dialogue open and hope we can maintain a respectful and open conversation. Lets the hope the data points provide the information needed to come to a definitve conclusion.



I appreciate everyone's input, and ask we all keep an open mind. Hopefully we will all learn something.

For the record, post 35 was by me. While it does show assembly at Van Nuys, the report text relating to front sheetmetal installation says:
At the time of posting, I wondered if the fender extension markings may have been relevant to the build details of the front end, perhaps relating to grille/headlight type, etc. and pertaining to the general process, rather than the location in which it was done.
Perhaps posting that was unnecessary, in which case please disregard and focus positively on gathering more data points.

Was it a style trim car? X11?
if so that explains the M. piercing the extension for the two screws unique to the wheel opening moldings.

FWIW The middle Yellow Fender Extension with only 427 and no additional Alpha code is Dave Beem's X66 YENKO (Bill Hunter car) so no fender extension piercings, no CUI call outs.
Which falls in line with the theory... 427 with M is style trim with R is Rallysport.

That’s pretty interesting that they coded the fender extensions .. Have any been observed on the VanNuys cars ?

For the record:
1969 Camaro, 12B Norwood SS/RS396 extension marked R6

Steve Shauger- would you happen to know what was on the fender extensions of your former SS/RS L78 Pace Car?
I have my original front clip still intact and I could not make sense of it last time I looked at it a year ago- with this data I will re visit and post the characters listed as with another SS/RS L48 Pace car 100 vins later- both 04C cars from Norwood

1969 RS/SS 350 12B Norwood
Left fender appears as 3R.

Here's a new one. Still going through old photos when time allows. From my old 69 10E of 69. 307 X11 with A/C

Appears to be O A M but I can't confirm as the extension is now gone.
