Does anyone know if I can put euro style plates on front and back, or just front. I already have custom plates, but if I put the same numbers on the plate I think that should work. I have found a service in Ireland that will also stamp a "slogan" on the plate, so along with the number I can have "Texas - State of the Arts" on the bottom of the tags. I've seen these in the Dallas area on front and back, but has anyone else had any experience with these?
