Julian Date Codes vs Cowl Tag Build Dates

[Kurt S]

Fisher didn't have hard, set rules on the weeks. It was for their purposes, Chevrolet never looked at it.
NOR was not consistent. You can try to force a calendar on it - square peg, round hole.

Go off the production date from the NCRS shipping data.

The April calendar week starts on a monday - so effectively that week could be considered 03E if we look at build dates - OR would it be considered 04A?

Im trying to determine the days of the week a car would be built if it was an 04C cowl date code.

Thoughts and help?

I don't think we can shoot that straight.

The Fisher codes are specific to body build only, and even then there is a margin of error, due to work stoppages, breakage, or general assembly down time.

Also - keep in mind it takes a few shifts for the body to get started and get through the body shop, and then through paint. Once it drops down into general assembly it can be completed within a few hours (likely that same shift). It can then still spend a few hours to a few days running around in the repair area before actually leaving the facility.

Really no way to know for sure unless you happen to be standing there as it goes by, or if you drive it off the end of the line yourself.

Unless the car sat in AGR or in the repair lot for some period of time after primary assembly was finished.
