can the hardtop be turned into a t-top

Short answer, no, not without a lot of expense and the possibility of weakening your car so that it will be dangerous in an accident.  Suggest finding a T-top car you like as you will likely pay as much to convert yours, if you can find someone willing to do it, as you would to get one with t-tops in the first place.

Like said earlier, you can do it with a donar car, but you'll have to strenghen your frame by welding frame rails on.

that would be stupid and a big wast of money for how much you would have to pay you could buy one with  a t-
