anyone have one like mine ???

Your car might have never sat out on a dealers lot. Back in that era so many cars were ordered with options chosen with a check mark drawn in the little box. Yep, mail order autos. The buyer would make a *** mile road trip to the nearest dealership to take delivery on the car they had ordered.
To top that... I still remember the day ( and that "wonder bar" radio ) when a dealership brought our neighbors new Buick to him.
Is there another identical to yours in every way? Maybe not.
