While I was under the truck the other day I noticed my 4" downpipe has been rubbing on the coolant line to the trans oil/coolant heat exchanger. I would like to replace this line when I adjust stuff under there to prevent it from rubbing since it has a big flat spot in it now that looks like it is going to start spraying coolant at any moment. Anyone know where I can find a replacement one? This is the hard line that connects on the rear most part of the heat exchanger and carries coolant not trans fluid.
