radiator help 63 dart 6cyl 170

Thanks for the the link. I just did a loose install of the 2 core (1" tubes) AE64dt radiator and found that I can't get the fan blades back on because the radiator is too thick. I'm so bummed! I think that 20949 lower radiator hose that you recommended would have been a good fit. Seems all I can do now is pay for the a recore of the original.
all the best
