I've been wondering the same thing, only with a '33 truck. Right now the truck has swinging pedals on it and because of this the firewall is all hacked up. I'd like to move it back under the seat, only I'll probably still use a hydraulic clutch setup as well which complicates things more. I have found a couple places that sell the setup for both, however I'm not sure how much hacking I'd need to do and the setup is between 300-500 dollars which is quite expensive for something like this.

I've also read someplace that a 39 Ford pedal setup will work with minor modification? Not sure on that.
