Radiator is leaking...replacement options?

You guys who found radiator at Oreillys, which one? Part #? When I called them they say they dont have any radiators, and that I could bring it in and they can send it out to basically be re-cored for $388.
Here's the one I bought http://www.oreillyauto.com/site/c/d...Search_radiator_5137387_1765&keyword=radiator
