I was chatting with a couple drag racing photographers (Tom West, Rich Welch) who gave me a big background on this type of ride. It was classed as "AA/MR" (Modified Roadster) until the advent of the Comp classes.
Daddyfink, I was thinking about the same thing but will probably have to build an entire new hoop to get the roll cage up past the top of the body, though. Not sure what I'll do for the mill, I'm going to make my kit close but probably not an exact copy . Truthfully, I have always envisioned one of these but never seen anything but fuel coupes.
