74 Dodge D700 brakes

I have a dodge D700 dump truck that's been sitting for a while. Brake cylinders are all leaking and will need to be replaced. Could someone out there with the knowledge can tell me where to start looking for the parts. Looking to buy new ones. Any help would be appreciated, Dave.

Try NAPA, they will have to order them but surprisingly they carry them.

ok thanks

The casting numbers should interchange to a good part number.I did this with my L600 and found Wagner cylinders for it.
