Another thought came to mind, that it also seemed like a perfect time to stamp a date code onto the front of the K-frame because those assembly line workers know exactly what day it is and what shift they are working and that date and shift code would tell just exactly which team of workers married the ENTIRE driveline to the body.
The K-frames were stamped on the day they were completed like every other date coded part / assembly if that helps at all?
Like any part or assembly, completion was required before going into a car.
