Decoding the Fisher Body Tag

I spent a bit of time this weekend decoding the body tag on the firewall and discovered several things.  As the body tag reads from top left to right:

01A = Body was built the first week of January (1966)
66 = 1966 model
13817 = Chevelle SS Sport Coupe
FL1 = Assembled in Flint, MI
2870 = Fisher Body Unit ID, this is the number assigned to the body, not to be confused with the VIN #
763-3 = Black Viynl Bucket Seats
M-M = Upper/Lower Aztec Bronze Metallic Paint
4F = RPO-Z19 Convienance Group

So based on the details I was able to confirm that based on the number of cars built in January in Flint that a reastic build date should have been January 5, 1966. 

As you can see from the body tag the color of the car is red

The two pictures above illustrate the correct aztec bronze metallic color and the one I'll be using for the car next year.   Based on my reading the color will change based on the type and amount of sunlight but overall I expect it to look much closer to the first image above.
