If you are talking about the adapter for the oil pressure sender, it is brass. As for the oil line protector, if you are talking bout the wire to the oil pressure sender, I'm pretty sure it should just have a black sleeve as thermal protection. There's a clip that attaches to the aftmost manifold bolt, to keep it away from the manifold.

What are you talking about when you say, 'hockey sticks on the quarters," and what is "COPO" about them? Not challenging, just curious.
