Moving to AZ Registration Questions?

You can also find a set of plates that were issued to a vehicle from 69 to 71. Yellow and black lettering. You can then take that down to DMV and they will assign it to your vehicle.
I did that a few months ago. But you must have both front and back plates. You only NEED to display them on the back of the car, but you must have both in your possession.

Here is an example, but I am in no way recommending these. they are the first pix I found http://tinyurl.com/hg4o9w5
