Here we go again, can’t really go by what the books say can we. My ‘54 cooling system is the original one. The numbers match, the year, it’s a 54C R-11 Harrison with the right part number. The original owner who bought it new in ‘54 was over last Monday to look at the truck and we talked about what was done to the truck over the years. So I’m 100% sure that the original radiator in the picture is the one that came in the truck in the spring of 1954, the new one is from US Radiator:
http://www.pbase.com/dennygraham/image/131160297/large Even though the grill was not punched out for a hand crank and the balancer does not have a dog for the crank, the radiator lower tank was still indented for crank clearance in ’54. Harrison must have needed to use up the surplus lower tanks.
All of the earlier AD’s (pre 1954) that I’ve seen with the correct factory installed radiators have had the radiators with the indented lower tanks.
