Hi Ron,
Here is the .DWG file for the taillight board. Be mindful of the thickness, I think I had it cut out of 14ga instead of 16ga, so the clips on the end didnt fit very well. It is a starting point for you at the very least.

For the bulbs, the stock lights use single filaments across the board. I used dual filaments for the brake and tail lights, as a effort to increase visibility. You can see this in the picture the sockets with the two wires. The dual filament sockets also have a wider base so I had to clock the sockets off the other holes a little and drill new ones.
All in all it works very well and I was able to increase the light output in the rear, something you cannot do with the stock tail light boards. I wired everything to a weatherpack connector to further ensure the lights have a solid connection. Something you can never be sure of with the stock setup.
