Your only thing that you will have to do, is make a adapter as the water pump outlet is larger than the lower radiator connection. I used a flex hose for a Rambler(American Motors),as it had both sizes and was the correct length. I hate flex hoses as they always seem to brake(but mine never did)in 10 or fifteen years. A better option is a rubber adapter ring, that most good radiator shops should be able to supply. Use your 1937 upper hose outlet(thermostat housing)for the size to math your radiator upper hose connection. You have to use the 1938 fan to fit the 1938 water pump(check the blade length with the 1937 as later ones were longer.
Every thing else is a bolt on.
