I don't. What I meant in my last sentence which probably didn't make much sense because I fast type without thinking is, just because I posted some nice hot rods now and then, doesn't mean I know a lot about them.
But you probably have gotten your answer in my second sentence. If I might go read about it, it means I don't know about them much. All I know they have existed practice by the 30's or 40's. Or maybe even in the 20's. It was like a whole new style for cars. When it happened, it's spread the world like a bang. In my theory, that is. Like, if you have built a hto rod or made a nice 40's or 30's ford look like one, I bet if you were in the high school, everyone would think you're one cool hell of a guy.
