Alright, so it looks like what I neeed is the hard water pipe that runs behind the exhaust manifold and then drops straight down to meet up with the oil cooler. If I had to guess, I would say it's about half an inch in diameter. Do you know which one I'm talking about now? Good, so who had one, and how much? Thanks guys.

 

I think I have one and I will post some pix tonight.
