With only six originals ever made (not counting the never completed one 427 version, continuation models) not a lot to choose from. Although I believe there are subtle differences, they are very similar in appearance to my eye. This video shows them all together. https://youtu.be/Qlhru1eh3cg. The CSX numbers for each are widely available, and you can find more details for each. Haven't ever seen one in person, but have seen enough pictures including the "creature comforts" that I took mine in the direction of a more modern build. That plus the Coyote power, color, etc. I chose doesn't make it very authentic. But still unmistakably a Daytona Coupe. Build thread in my sig line below if you haven't seen and are interested. Should be done in the next month or two. Good luck whatever you decide. Fun project.
