I was at the International Mustang Meet in Red Deer,Alberta over the Labour Day long weekend and took some pics of a very original, except for exterior paint, 84 1C, 5EF135869. It had a "G" stamped on either side of the core support, both sides of the inner hood and also on the hatch. First time I've seen it on a hatch. Also had "12 01" on the inner fender and bumper cover and the build date for this vin is 1/12/83.
