Where did you get those plates? You will never be able to register that plate..... It is a 69 stamp and not a 63. Not to mention the 69 stamp is in the wrong font and font size. YOM ONLY allows the 63 stamped plates. Sorry to break the bad news to you.
1963-1969 plates have a 63 stamped on them NOT a 69. Here is a closeup of an original plate showing the 63 stamp.
