Thats the pic that I'm gonna whip out the next time someone tells me that a T-Top is just as strong as a hardtop. (IMG:

I've actually seen quite a bit of debate about this. I'm actually of the opinion that a hardtop is just as structurally sound as a t-top. Take a look at that picture - the internal supports are the exact same thing I have in my t-top car (not partial to t-tops - there's a lot that can be done to the car below the roof before the roof design becomes a deciding factor in stiffness).
Sure, a hardtop car has some sheet metal that is bolted/welded to the structural components. But, does this sheet metal really enhance stiffness? To me, it is like replacing metal body panels with fiberglass or plastic. The underlying frame is the same, so the stiffness is the same (or so close as to not be measurably different).
About the only thing that would make a big difference is if a hardtop car had some kind of bar that went from the windsheild pillar to the sail panel (where the handle is for a t-top). Now, that piece would help a LOT!
