I could sell you the speedo sensor, but that is actually better bought brand new. They seem to fail based more on time and less based on mileage. They seem to last around 15 years in this case before getting erratic.
The big plastic right side cover on an 04 is asphalt black, not gunmetal, from the factory. I also don't think I have any of those. There's a silver/gunmetal metal heat shield mounted to the airbox assembly, is that what you're looking for?
Yea, I looked on a blowapart and the color is called gunpowder. But thanks for being honest. I will go the OEM route.
