There is one guy that makes them. I think its hairyglass or something like that, not sure exactly. Only problem is the one he makes is only meant for race cars, so it doesn't have the provisions to bolt on the tail lights. You could probably make it work by cutting that section off your original trunk and welding it in place across the back of your car and bolt your lights to that then either use pins to hold the trunklid down or fabricate/modify some latch to work.
