I've never payed close atention to how the radiators look (On NS, all we have are spartan cab SD70's), but in looking at the photos, I would not use an SD45 radiator section. To me, it looks like the radiator grilles and fans are the same size as a regular '70, so all one wold have to do is cut out a section from the rear access doors up, glue it back in at an angle, and add styrene pieces to fillin the gaps. The front is straight (unlike the SD45, which is tapered), and the back simply follows the angle of the rear.
