75-77 cowl tag codes project...

I know this is an old thread and I don't know if this helps, but these are from the Fisher body manuals for 1975 and 1976 ('77-'80 are the same as '76). The manual calls these numbers the "Schedule and Item Number", but I don't know what that means.

By the way, the schedule and item number also show up on the build sheet. Box 1 contains the chassis schedule and item number. Box 11 contains the body framing schedule and item number, which should be the same as on the trim tag. You can see from this file on Bryan's website, that the chassis schedule and item number is the first number on each line. The schedule numbers are the same and the item numbers are sequential (even across all GM divisions).

""the "Schedule and Item Number", but I don't know what that means.""

The schedule number... the first digits, are day the car is scheduled to get assembled. (it's not a calendar date...it's a production day that the plant has determined, they go in sequential order.. starting at 001. There are about 20 of these days per month). The second number is a tracking number. This keeps the cars in a sequential line... so no matter of the make and model or different vin's.... the line could stay in order... and production could be traced in case of a recall involving cars made during a certain time period. Such as, a robot missed 500 spot welds before anyone noticed.

St Therese cars and buildsheets (seen above) used an XXX - XXX format... Lordstown used a XX - XXXX. The actual corresponding calendar date can be found in Box one of the cars buildsheet.

A car built on the last day of 1978's cycle will have a 44-XXXX Since the cycle that year lasted 244 days.
