The rear of the radiator support is how the factory mounted the radiator, like in my second picture. This would normally place the fan blades of a late model 235 into the radiator (as Hot Rod Lincoln has previously pointed out). There is something missing from this equation that we are not seeing.

If the new pump fits the engine block, that confirms it a late model 235. I have the water pump I replaced from my ‘59 235 and when I get home, I will measure the distance from the pump casing to the end of the pump shaft to see if the fan hub has been pressed back.
