I shifted back to the electrical system; I have to wait for my bucker to get started on the wings. I need a way to attach a map light to the roll bar, I did not want to drill another hole into the gusset of the roll bar so I made a sandwich of aluminum disks, a smaller disk will fill one of the holes in the roll bar, while 2 larger disk sandwich to the roll bar itself to hold the mount in place. This seems to provide a nice mount for the map light. It will be pop riveted in place so I can just drill out the rivets to remove the mount. I test fit the mount with the top skin, there is just enough room to get a wrench on the nut in back if I ever have to replace the light which I think is highly unlikely since it is an LED light.
