Build date question

Yours is a 67, the last year that Chrysler kept the build information. Send them $45 and they will send you a letter along with a copy of the build card.

The scheduled day of production for my car was 5/31/67, which is the date that was placed on the fender tag, but the car was actually shipped out on 5/26/67. Both dates are on the build card.
Apparently, the scheduled date was just that, but most cars were produced prior to that date.
Which makes sense as it was ordered, and other parts on the car support that, like the assembly date on the engine of 5/23/67.
So, my assumption is the car was completed the same day it was shipped.
