Longhorn Man, you made me think! I used these rivet nuts to mount my cargo light and it works correctly, I have been trying to remember how I made it work.

You are correct about the metal bolt into a metal fastner in a metal body creating a constant ground.

What I did was I put an O-ring or some other type of rubber piece on the bolts to keep from grounding the bolt to the cargo light housing.

Works like a charm for a couple years now and really easy to put the cargo light in.
