Do all 3dr wings have date stamps on the top of the wings?

Just went and looked at a 3dr and one of the wings didnt.

Just wing looked original, the mouthing rails looked untouched, the factory seam tape on the front panel was untouched, the mouting was perfect and underneath the underseal looked original.

Very strange i thought all 3dr wings have ford badges and dates stamps.

Do they?

It was the drivers front wing if it makes a difference.

Alos the slam panel was original and ford stamped and date marked and so was the other wing, but not this one.
