Marty....I am somewhat amazed that the pedal will not depress as the leverage applied to the fingers on the pressure plate by even light pressure of your foot is great. Get a couple of your friends and try rocking the car back and forth while trying to depress the clutch. By the way, did the clutch work OK after the rebuild? I am not familiar with '33 Chryslers; however, there might be a removable inspection plate under the floor board or on the side of the bell housing that will allow you access to the pressure plate and clutch.
