I need some help identifying which knob goes where on a '40 Ford dash. When I bought this car it had an aftermarket dash in it with Stewart Warner gauges so I'm basically starting from scratch in regard to an original dash. I've got the dash and steering column installed and am trying to figure out which knob goes where. I know where the starter button and the wiper knob go but after that I'm at a loss. Somebody somewhere must have a diagram of a '40 dash they can steer me to....... I hope. Thanks in advance for any help.
