is this a real demon?

Exactly. I'm pretty much always "looking", I have some kind of disfunction when it comes to searching the internet for cars. :D I've seen a few Demon projects here in northern California semi-recently that were $2k or less, but all of them were in pretty rough shape. Which is why I bought a '74 Duster and cloned it over to a '71 Demon. Cheaper and easier, believe it or not, to start with a clean '74 Duster and clone it than it would have been to repair any of the Demon's I've seen in the same price range.
I've got a worse one for you...A 66 Marlin. I've been looking for roughly 20yrs. Only one I've ever seen was my father's. He's been looking for another for about 30yrs.
