I got mine from 1800-radiator... They get mixed reviews, but I use my truck as a daily driver and after 3 years in the mountains (-10 to 30* in winter and around 50-80* in summer) it hasn't given me any trouble at all.
Radiator was like $229 it is STEEL and not cheapo plastic. It was an awesome deal as everywhere else was like $399. I live within 30 minute drive of their warehouse - but I had them ship it. THEY SHIP ALL OVER USA.
P.S. it's worth it to spend $15 more and do the thermostat at same time.
