The bottom pic is all Plymouth, so that's not a tube Ford axle...
The axles, front and rear, of the car I want to build are simply just as Ford made them from 1933 or whatever to 1948. The brakes were changed in 1940 to hydraulic and the stud pattern became the same as the F100... rather than having the wheel studs out on the perimeter of the brake drum.
These brakes are what's now hard to find here. Are they easy there?
Yes, these types of cars are raced here and participate in a lot of street demonstrations and the like. I would also make up cycle fenders for mine as it is made like a 2-seater and use it on the road.
