Aluminum Year of Manufacture plates illegal

There is a license plate maker in Florida who advertises that he will make YOM plates for your car which the DMV will accept. Be advised, this is untrue. I should have read the pertinent parts of the California Motor Vehicle Code before I bought these. The Code provides, first, that only the state can manufacture license plates. Second, the Code says the plate must be made of steel. When you try to call this guy to complain that you can't use the plates, his wife answers the phone and he never calls back. My dumb for not reading the vehicle code first.
