I'm curious about the DY in the upper corner and the two segments of numbers past the manufacture date 07E
Also, I have read that the B80 is for the black vinyl top and also read that it's the drip rail trim...?
I appreciate any help

Found the following on the Chevelle Stuff website
Not sure if its the same as Pontiac

Data Processing Numbers

Fremont:
The first 6-digit number can be found in block #24 (MANIFEST SEQ. NUMBER) of the build sheet.
The second 6-digit number is actually a combination of a 2-digit number and a 4-digit number. The first 2 digits are found in block #10 of the build sheet (SCHED NO) and the last 4 digits can be found in block #24 of the build sheet.

Thanks for the help. I've only owned the car for 5 days and I haven't looked for the build sheet yet
