Otto, I would not even consider doing such, nor would I condone anyone else doing so unless their state laws allowed such "replica" plates. Missouri regulates YOM plates and registration issuing and use/transfer and has set standards which you can read about
HERE. I am sure other states have similar legal requirements, and would expect that anyone that is driving their trucks on our public roads would be sure to have their vehicles properly licensed/insured per the laws of their state.
If (BIG IF) my truck was going to be a display piece that never was driven on the road, or I wanted something to display at a show that was only put on temporarily for display purposes and then removed and legal plates put back on before driving, I might consider it. On second thought - Nah!
On an update to my earlier post, I reread the MO YOM rules and details provided by fellow Bolter Shakey61. The single plate I have has the sequence NN-NNN, and if the State of MO can confirm it is valid and not in use by someone else, I could get approval to use it legally once I can find a correct 1951 metal year tab to match my truck YOM.
