Starting in 1975, passenger cars received "First In Freedom" with 3-letter/3-number format and received renewal stickers. "First In Freedom" was dropped in 1978, but numbering system continued in alphabetical order. Date of issue began being stamped on the plate in 1979.
Truck plates continued to be replaced annually. Numbering format was 2-letter/4-number. All of these have the date of issue stamped in the plate.
Any of these can be legally run as YOM whether it is a car or truck as long as the title of the vehicle matches the year displayed on the plate
