I did this on a '41 1/2-ton 30+ years ago.

What I remember was swapping the drums, hubs and backing plates.

I think I used the inner bearing from the truck hubs and the outer bearing from the car hubs.

Those old car brakes are going to be tough enough to find that I'd investigate using more recent brake stuff instead.

When I converted the front of my '55 1st to disk brakes I used '73 Chevelle disks. Outer bearing was the one that came with the disks and the inner bearing was provided by the vender I bought the kit from (along with a collar that made it fit the spindle). The spindle nuts from the Chevelle fit my spindles.

I'd bet you could use a similar approach to adapt drum brakes off a 60s GM car with drum brakes.

It's true. I really don't do anything but browse the Internet looking for trouble...
