Here's a page from a 1967 Chevrolet monthly shipping report. The information provided on the
Chevy Muscle Docs is shown. The other data was not made available.
Also interesting is the page number 271. There are fifty records per page which suggests the report has ~13550 cars at this point. Perhaps this report includes all vehicles for the St Louis plant that month.
I expect these shipping records also vary by year. Sometime in 1968 or 1969 the computer systems were updated. This is also seen in some of the other paper records.
