Did the dreaded passenger exhaust manifold gasket change over the weekend, and ended up with a spare nut that I think I've narrowed down to the starter. The nut is cad plated, unlike anything else I had removed from the truck. Does the starter stud have a nut, then starter ground wire, then another nut? Right now I have the ground wire between the starter and the nut. I can't seem to find a picture online of a starter up close to show this.
