Cold Case or Griffin radiator in a 1970 Duster?

1970 Plymouth Duster with a 360 and automatic transmission. I'm looking at the Cold Case MOP755A or the Griffin Exact Fit Radiators 5-70154. I have hard lines for the transmission cooling lines. Would be nice to have to tweak as little as possible. There is quite a difference in price of the two radiators. Any of you guys who run any of them in a Duster with automatic transmission? How do they fit? Read that some people could not close the hood with the Cold Case, and had to modify the lines for the transmission.
