I am curious if any one has looked at the golden ratio for hotrod design? I found this on new cars but have never seen anything for hotrods. https://www.goldennumber.net/carwow-beautiful-cars-golden-ratio/ There are many threads on how much to chop a top. The coolest ones, in my mind, have windows not even close to the golden ratio. In fact they are close to the golden ratio squared. (2.8) And, yes, I do know that my mind is not wired to look at the world in a normal way.
