Frame for my 1955 license plate (13 1/2 " X 5 1/2")

[Guest AWBE]

Alabama is now allowing vehicles over 25 years old to have tags of the same year as their license plate. I have a perfect 1955 tag to go on myy 1955 76-R----But can't find a frame for it. The Feds mandated in 1957 that all tags be the same size.(12" X 6"). Has anyone been able to find an adjustable frame. I've worn out GOOGLE looking for one.
