I don't know for sure what year Texas went to dual plates. However, if your classic vehicle predates that date, and would only require a rear plate in that year, you may use a YOM (Year of Manufacture) plate. I have one on my '53 MG. Basically, you find a genuine Texas plate, in good condition (found mine on eBay), and take it to the vehicle registration office in your county. They look up the number in a large book, verify it is a genuine TX plate number, and issue you a new registration using that plate. You pay the normal registration fee + $15 additional each year. There are no restrictions on these plates as there are for the "Antique' plates. They are as legal as any modern plate on any TX vehicle.

PS: The reason you have restrictions on the "Antique" plates is that you only pay a small fee, rather than the normal registration fees, so you are in effect saying I don't use this vehicle on a regular basis, and I only use it for shows, parades, etc.
