According to the list Veronica has going here. http://www.allfordmustangs.com/forum...-vin-data.html
Your production date would be a 27G or 28G. You might want to double check the color code though, before making the tag. Putting it into the decoder states that its not a valid color, but looking through a restoration manual states that 7 means Phoenician Yellow, which looks to be almost a very soft cream yellow.
Are you planning to go original in this car or restomading it? I am restoring a 64 1/2 convertible myself and just got done dealing with cleaning the rust out, need to start a resto thread i know, and have found a few interesting things so far. People here are great help. Right now I'm finishing up my generator rebuild and found some things with that. If you decide to keep the generator, if yours still has it, let me know and I'll give you info that I found there.
