03 Legacy AT trans cooler lines?

Hey guys,

So I was changing the oil on my car earlier, and noticed one of the HARD lines, that run over the front driver side wheel well (inside the engine compartment) is rusted. Right before it meets up with the rubber hose connected to the trans cooler. Sorry if this seems scattered, just let me know and I will elaborate a little better.

For the life of me, I cannot locate those hard lines anywhere. Autozone didn't have them, O'Reilly did not have them. Any ideas? My thinking was that I may need to get the correct rubber hose and join the 4 ends together.

Not the best pic, but it's an example of what I'm referring to.
