Where can I get a power steering gearbox for a 1956 Dodge custom Royal
The 1957 Ford Thunderbird came from the factory with power steering. If the unit is not functioning properly it may be unsafe to drive it. So, yes, the system should be fixed if not propelry working. If you located a 1957 Thunderbird that did not have power steering factory installed, there is no benefit to doing the extensive work to fit the equipment, and it will lower the value of this rare car you found.
this can be a number of reasons for ex, power steering ,altenater,or oilpump
either rebuild or replace gearbox.
Well, have you actually done any sort of diagnosis? If there's no fluid leak visible, and there's fluid in the reservoir, then you have either a faulty power steering pump or gearbox. So then you disconnect the line from the pump to the gearbox and run a pressure test on it.. if that checks out, then it's probably your gearbox.
Rent or buy power steering puller/installer from parts store. you will need to make sure it is a REMOVER and INSTALLER

Ask your local Ford dealer for a shop manual.
Remove the power steering pump bracket. It can be done without dropping the rack.
Either buy a rebuilt gearbox and replace it, or buy a gearbox rebuild kit and follow the instructions to rebuild it.
