Some previous owner cut open the radiator frame/housing in order to move the radiator away from a later 235/261 engine's "protruding" fan blade. This was a very common operation/surgery.
If you want to put a original-style radiator with an engine that has the water pump in the original location, you should look for a 1954/55-1st 1 ton truck's radiator housing.
You could use a 47-53 1 ton truck's radiator housing, but the horn-mounts will not be found on those radiator frames.
What year/size/vehicle engine do you have?
Added later: T54X engine? That would be a regular 1954 3100 truck 235 engine (made at Tonawanda).
T54XA = 3600 235
T54XB = 3800 235
