My ‘40 convertible has a large radiator cap, which I assume is correct. My problem with it is that my pressure checker does not have an adapter to fit the neck. Does someone make the adapter? Sid
 
If you have a stock radiator you’ll not be able to pressure test unless you block off the overflow tube.
 
dont know which tester you have but check with them often the adaptors will only work with their tester only
 
As Ken said, the stock radiator isn't a pressurized system. If you are chasing a leak I wouldn't try to add more than 3 or 4 psi or you risk damaging the tanks that weren't designed to hold pressure.
 
Ford was in development for the pressurized systems but didn't get there for a few more years. Some later aftermarket radiators may have a bung for a pressure cap but the originals didn't.
