This is a reproduction in aluminum of a data plate known to be correct for 1953, 54, 55 Mercurys. It is probably good for surrounding years, but I do not know which ones. This plate is flat while the original one had a raised border. Original stamping was embossed. I can emboss this plate for you for $15. Plate size: About 4.25 x 2.125 inches (can custom make a plate per your desired size)Thank you.
