Re:Heater and Ac tubes that run behind the firewall

I took off the heater and Ac box /core last night and found the internal part of tubes that run inside the firewall rusted. I was wondering if these parts can be replaced. I couldn't find them on LMC. I'd rather not have to replace them, but since I'm running all new hoses and tubing with my new engine, I would hate to see whatever crap is inside there running through my new radiator and engine.

I'd be curious to hear peoples opinions if they should be replaced or just run with what I have.
