Vin number question

We do not have the 1964, '65 or '66 Dodge TSBs on HH yet but here is a link to the 1966 Plymouth page - https://www.hamtramck-historical.com/images/TSBs/1966/66-1_page2.jpg

As you can see, the Hamtramck A bodies for '66 started at 500001.

They were also built in St.Louis.

And...... these cars were NOT built in VIN order regardless of plant. ;-)
