My problem is the blacked out area of the window where the current 3rd brake light mounts is fused to the glass. I've tried everything I can think of, paint remover, alcohol, MEK, acetone, etc. to get it off, nothing has touched it. My next step is to find a OB rear window glass. Any suggestions on how to get the black coating off the glass would be greatly appreciated.

I like that idea better, no cutting.
Somebody was selling a fiberglass GTS spolier copy with an LED third light on ebay a while ago.

Glack,
You will need to pull the wires to the hatch as Dave says - how will you work around the bulb monitor issue? On my GTS the high stop lamp is just in parallel to the Right stop lamp...? try that first...
Another option is to use an additional relay to drive the new brake light with its coil connections coming from the right brake light feed.... the coil only takes <200mA - so probably within the tolerance of the brake light current monitoring... if not feed it directly from the stop light switch before it goes to the bulb monitor.
You'd want the relay fed from an X-Bus or 30 Bus (always on 12v bus) supply so the brake lights will always operate together (they use X-Bus). You could probably do this at the back of the car or at the Central Electric panel.
