I managed to get my hands on a hardtop for my Sport. It is a direct bolt on and the connection for the brake light is there. I removed the original brake light that's mounted on the spare tire. However, there is still a bracket that remains on the carrier but that is hidden behind the spare.
I used the wiper motor's gaskets to cover the hole for the original brake light. Since there is no wiring for the wiper or defroster, I just didn't mount the wiper or it's motor, haven't had a need for it yet. And yes, wiring it in would be very difficult.
