Demon "Classic Air" AC Install

Has anyone used one of these units with the factory ac venting?

I am wondering the same thing, if you can install the hoses onto the factory A/C 3 louver box if the rear of box is modified.

That's what I want to do, as well as maintaining the passenger's side fresh air vent too.

6pk2godemon, is there enough room beside the Classic Air heater box fan to install a cut/modified passenger side fresh air vent on that side?
