Even for my 1959 2.5 ton I was only able to find off-the-shelf wheel cylinders for my truck. I took the drums to a machine shop to get them turned and re-used the old pads.

Your best option is to find a service that can re-line the brake shoes, or learn how to do it yourself. Unfortunately with this age and size of truck, you are at the limit of what can just be part-swapped.
