Forget T-tops. I still remember a long wire story I edited back in the '80s about several kids who got killed in a Trans Am with T-tops. Their families finally were able to prove in court that the T-tops has basically destroyed the structural integrity of the car. Apparently, T-tops are cut out of the existing roof when the car gets to the end of the assembly line. Hence, like many convertibles, the car actually isn't designed to have them. I'd just as soon have as much metal around me as possible.
