A well-known Mopar aficionado posted
this info awhile back. I have found this to hold true by looking at hundreds of fender tags and Scheduled Production Dates (SPD).

So, just how many cars were built at Hamtramck per day in 1970?
Well, there is no way to know for sure, each day would have been different, but we can average the known numbers and get close.
The VINs assigned started with VIN 100001.
The highest VIN currently known is above 443001.
The 1970 model year ran from August 1st, 1969 until July 31st, 1970.
So we know that at least 343,000 cars were actually built on
Hamtramck's two assembly lines.
If we take 365 days a year, minus 104 for weekend days, that leaves 261 days.
I am not sure what holidays were allowed off, but we can safely assume five I bet? That leaves 256 possible production days.
343,000 cars divided by 256 days gives us
an average of 1339.84 cars per day from this plant.
