You can easily find the two speed motors and switches new. Classic Parts is one place that has them, others do too. The really hard part is finding the knob that has the washer button on it. Only one I have ever seen on a '63 is the one off my C20, and that's being saved to go back in. Also, take a look at your wiper motor first. You may have a two speed motor and a one speed switch. Yes, this is how my C20 was set up and it still had the original parts. Kind of weird really, it had a one speed wiper switch w/ washer.
