That's the best modified box I've seen yet. Well done.
The glove box they send with the unit obviously doesn't fit at all. I don't even know what they were thinking with that. There's ill fitting and then there's the classic auto air glove box which is in it's own league.
Did you tackle the driver side vent tube issue yet? If so I'd love to see how you have your hose routed back to the box.
