Source for coolant lines?
It's a 3-way hose that runs from the radiator to a 3 way splitter on the passenger side of the car. The "system" is a combination of aluminum tubing rubber hoses, which are crimped together. From the splitter, it runs to the firewall (to the heater core, I presume) and to the bottom nipple on the coolant reservoir.
I took some photos, in case my explanation doesn't make sense, sorry for the crappy cell phone quality:
Where the hose connects to the radiator, at the upper left (passenger side):

Then it runs to a splitter, toward the back of the front passenger side tire:

Where it connects to the firewall:

Where it connects to the reservoir (it's the bottom hose, marked "lower"):

I couldn't find anything like it at Eckler's or Corvette Central (or any of the other vendors I could think of). Is it something that can be ordered, or should I just replace the whole think with plain Jane coolant hose?
Thanks for any insight you can offer!
The hose neck on the radiator should be 3/8 and the hose neck on the surge tank (with radiator cap) should also be 3/8. The connection at the rear of the engine is not the heater core but is a return line from the engine. That you will have to measure as I did not have that setup but it may end up being 3/8 also (hopefully). Buy some Goodyear Hi-miler 3/8 hose on Ebay or 3/8 silicone hose. Either choice is expensive but I could not find any other alternative. Then buy a heater hose tee in the correct size (NAPA, Dorman, etc.) and connect the three lengths of hose together. You will have to reuse the factory hose from the surge tank to the white overflow bottle because the headlight will not open correctly (it will rub on a replacement hose - I found out the hard way). Just drill out the connectors and separate from the other hose to reuse.
Good luck.

Then at home cutoff what you don't need.
I'd rather have a new hose that fits OK rather than a used hose that fits perfect.
Explain that logic to yourself when your headed home on a flatbed.....
