The trim tag was one of the first dated items installed (sheetmetal was also dated). The car was still days away from completion when it was attached. Had barely started thru Fisher Body.
Engine plants (and other component suppliers) received a weekly build schedule (along with some build projections). They wouldn't even realize the volume on a small runner like COPO's was reduced. And since it was a standard engine for them, just with a couple of Camaro-only parts, volume wasn't an issue.
