Strange code on 1969 Barracuda convertible fender tag

Thanks for the pic 1958300!
Does not look real functional- and as was said... a pain for any passengers in the rear seat.

How about the 2yr old sittin in the front seat with a lap belt????

In 1969 the child would not even had the lap belt on. He would have been standing in the seat by his mother! The belts would have been pushed into the seat out of the way.
