Can't believe I didn't think of Koyo. I used a lot of their stuff on my Nissans in the past.
However, no one locally carries Koyo (especially at 9:00 pm), so being pressed for time I went with a Spectra Premium from Autozone. It fit EXACTLY like the factory radiator - all mounting points for the fans and to attach to the car are identical and fitment is excellent. It's got a lifetime warranty but hopefully it'll serve for a while with no problems.
