... I remember back then there was also a company that made a one piece polycarbonate roof/back window that was as close as you could get to a convertible without cutting the door frames.
The Slate Truck's rear window appears to be removable. Removing both the sunroof and the rear window would create a convertible-ish experience. My family had a 1972 Corvette with T-tops and a removable rear window. Removing the window improved the T-top driving experience more than you might expect.
Realize you’re looking for a removable roof over the cab, but I’m at least stoked the square-back has a removable roof. Any word if the fastback will have it?
