Prelude radiator fix?

The radiator hose on my 98 prelude was leaking tiny bit at the point that it meets the radiator. So, when i went to tighten it, the plastic at the point that the upper hose meets the radiator cracked all the way around, and left the fibergl/plastic inside the hose. Do I need an entirely new radiator, or is it possible to find just a replacement "upper rail"...the part with the cap on it that you unscrew. Any info is great...thanks.
