I've had to replace the worn out non GMC truck radiator with a new correct style GMC truck radiator . The problem is the fan is now in Contact with the back of the radiator

. Is there a short shaft water pump made for the 1952 GMC 302 6cyl ? I am not a engine whiz but would the 235 6cyl short shaft water pump fit the 302 ? Any help to this question would be happily taken . Thank you ED
