OK, I upgraded those c-clip retainer type transmission-to radiator/cooler lines with a direct-thread kit. Unfortunately, the new kit uses rubber-type hose for the entire length. I currently have the hoses wrapped with exhaust wrap to prevent them from being damaged by the exhaust manifold and downtube, but want to use something more foolproof, like a heatshield. For those of you who have done this upgrade, what did you do ? Thanks.
