Hi
That's incorrectly identified as Chantilly Green, I'll attach an accurate picture.
On the matter of the data plate:
20 is Chantilly Green
87 is Lime Green Leather
103 is the top code. The book does not give us this information, but the choices were: Black/Black Trim. Black/Red Trim. Blue Gray/Blue Gray Trim. Gray Tan/Gray Tan Trim. Green/Green Trim. I may get an answer on this later.
7 is the day of the month assembled.
E is the month assembled
30 is the 30th car produced on that day.
