One of the 'ideas' that I had way back when was to take a wagon, chop the roof right between the first and second set of rear windows, graft on a Mustang II deck lid using the lower part of the rear door as part of it, and have a sedan with a huge trunk. But, then I realized it would make the car rather square-ish, and would probably only look good as a 79-80. This would make it look much like a two door Fairmont, though somewhat smaller. You could base a convertible on something like that, but the issue would be getting the 1/4 windows to roll down or something. There have been conversions of the Mustang II, but they usually omit the 1/4 windows, which I think makes the side of the convert top look fricken HUGE. On a regular Pinto sedan, this would be even further exaggerated due to the length of the 1/4 windows in relation to the overall length of the car.
