Parts for old Wah pedals?

Having given up in my search for a cheap wah pedal (and when I say cheap, I'm talking about the 20.00 variety) I've decided it might be easier just to clean up and fix my old National Fuzz-wah from the early 70s. Basically, other than a few missing screws, all I need is the hard rubber gear that goes on the roller shaft, the part the arm from the pedal itself meshes with to roll the pot back and forth. Is there a good place to find parts for old pedals online?

Antique Electronics has a lot of parts like that. They're in Phoenix, AZ.

Thanks, Paul. I'll give them a try.

And I just checked. They have the whole pots with the roller. Thanks again!
