Just sharing some plates I made for my vehicle here, free for others to use if they wish so. Also wouldn't mind making more on (specific) requests. (Let me know which state and year though, and if for a civilian or certain emergency service car.) I've so far only made them for SZYM vehicles yet, but can do other vehicles too, only need to see what I need to work with. Else aligning issues may occur.

Also, feel free to correct me if something wrong, I'm Dutch myself so got to do a lot of research to get this right. Reason why I make them is because I'm a nit-pick with details, so any tips are welcome.

Now the following are based on 2014's 200th anniversary of the Battle of New Orleans plates. According to the wiki issued from Januari 2014 till December 2015, going from XSA000 to YPN999 as of December 2014. I assume that means they start with an X and then the second letter goes from S to Z, then the first letter becomes Y and the second goes from A to P. Third letter can have any range. (If so, then they're a heck of a lot easier than Dutch license plates.)

I have already uploaded them, providing the UUID's here for your convenience.
