i'll second that, but late 30's did, and i know it's been talked about, but i think the late 30's stuff bolts on....
If you are going to bolt anything on use at least the 50's Bendix brakes, they're lot better than the Huck brakes.
hmmm, been doin some reading...looks like theres some various options for bolting juice brakes on. Has anyone run mechanical fronts and juice rears before? Im not sure if I want to pick up this '33 front axle or hold out for a later model one.
