If I understand what you are looking for there is a line of 4 (0000)circles that point towards the right strut tower on mine, and I know they are original.
first 0 is a 5
second two 0 are blank with dark blue paint in them
third is an A I believe
so its 5 0 0 A.
Not sure if that is what you are looking for. I don't want to twist them around since they have been there for 15.5 years.
I had to use a flashlight and a magnifying glass to see them
.
