A friend suggested that I should move my 3rd brake light to the interior like he did. Well he never gave me any pictures so I was on my own, but I think it turned out rather well, and will look MUCH better when I get the panel covered.
In this picture you can see my 3rd brake light, the panel I'm mounting it to, and my custom spacer I had to make. The panel is curved and the light isn't so I had to fill in the gap so it didn't look stupid. My panel consists of 4 layers of cardboard that I eventually covered in some black vynil so that it looks a little better.
This picture you can see my 4 layers.
This picture and the next you can see the holes I had to make to install it and put the wires through.
Here it is put together. The stock bolts would not work because they weren't long enough so I had to go find some in my "random bolt drawer" in the garage. The ones I found were bigger around then stock so I had to dremel out the holes some.
Here it is installed. I did figure out that the bolts I chose were too long to mount the panel in the roof. To compensate I just drilled 2 holes in the roof. I didn't go through the top layer, where I drilled was in line with the clips that held it on the panel originally, so it was no big deal.
