Just finished up a project on me '06 Orion. Anybody have any idea what the cable guide rod might be made of? It's not a solid rod, but a 3/8" O.D. tube. It's definitely some type of steel, not aluminum, and seemes to be uncoated, bare metal, but it hasn't shown any corrosion whatsoever. Doesn't LOOK like stainless. Can't see why they would make it out of tubing, and leave it open to corrosion unless it was stainless, though.
