Yeah, Karen said the pan looked chopped up. Without the wheels, I can't properly ID it. The sprint had 6" wheels in 1970, but those wheels/tires look really small in that frame. My guess is that it was a Scrambler with the 10" disk wheels originally. Whatever it was, it didn't have a lighting kit on it. What year is the engine -- it's obviously not a 70 (square shroud), but I was curious.
If you decide to part it out, I might be interested in the fork lowers.
