Engine Coolant Bypass Pipe

[Scanman88GT]

I'm looking for a coolant bypass pipe for my 88GT, 2.8. It's the pipe that runs from the front of the coolant recovery tank along the inner fender on the passengers side, makes a sharp right right turn in front of the steering rack and goes to one of the heater core pipes sticking out of the firewall.

Mines got some nasty bubbly-looking rust in the bend area in front of the rack, and I don't think it's gonna last much longer. If you can give me a price shipped to Iowa zipcode 50213, I'd really appreciate it.

Thanks,
