'67 Valiant 2-door Hardtop

There's some amazing things going on there! How'd they make it a hardtop?! Cut custom quarter glass and then use the dart 2-door hardtop doors? I'm also eyeing the rear wheelwells....I guess those are the same as all the others. They appear fuller. And is that a '68 front side marker light there? I'd love to see all the minor details and differences.
