Check out the Explorer. You'll need hinges fastened to the glass, a compatible gasket, some kind of lock, and the gas struts. Cutting down a tempered rear glass may not be an option at any glass shop, but putting holes in existing glass can be done, as well as salvaging a compatible setup from another vehicle.
Anything can be done, it's finding the easiest/cheapest that works. With a 96 up, if the tape measure says it can be done, "just" weld in the window hole and bolt it all up (easier said than done.)
