Try searching this has been discussed before. Basically the answer is stay away from these conversions. Honda put a lot of additional structure into the T's to stiffen them including thickening the sections several chassis pieces. No matter how many braces an aftermarket vendor installs they can never achieve the stiffness that the factory thought was necessary for the T top. If you really want a T keep looking until you find the right one. Your car's value + $8500 (conversion cost) should get you a decent car.
