One other issue for some, is the aluminum radiator is straight across the bottom tank while the 1953 and older original bottom tank has a V notch in the center of the bottom tank for the hand crank to clear the radiator. I did not like the radiator cap that was included with the rad I bought (replaced with 4lb cap). My installation is in a 1954 1/2 ton with a 1957 261 engine. I am using Pre '68 Dave's pump relocation plate and an older style pump to move the fan up higher on the radiator core. Thank you, Pre '68 Dave, for your great solution to the installation problem of a newer style engine.
