70COPO said:The Machine at Fisher Body used to make the tags was called a "Graphotype" and had a card reader that used paper punch cards that were generated in advance by the central IBM 360 computer located over on the Chevrolet Side of the plant .
This type of error would likely be a simple punch card feed mis-position meaning that the mechanical card reader read the card wrong and then the Graphotype typed the plate as the card reader indicated.
On August 22, 1994, I looked at a 70 Z28 for sale at a Sunoco station in Milford, NH, with the "NOW" stamping on the trim tag. Note that the tag was made in the 2nd week of May 1970, just like your trim tag.
The trim tag was as follows:
ST 70 12487 NOW 298096
(2nd week May 1970)
VIN : 124870N539874

Wow, how do you remember what you did on August 22, 1994?
Why would a Astro Blue exterior be special order with a Standard blue interior?Previous threads here on Nasty suggest that the Z added to an interior code on the trim tag identifies an interior color that wasn't normally available with the exterior color on the car.
This link shows the interiors readily available with paint 25.
It would have been a special order color combo.
