Passenger side air vent

Always integrated into the heater box, I have never seen it any other way but a heater delete owner could chime in as to What they did up there it could be interesting.

I have a RB block so I am choosing NOT to use a heater core/box... that said the other day I took my drivers side fresh air vent and put it up in/on the passenger side and it has the same opening diameter with the exception of the studs the drivers side has so I will use a nut/bolt application along with a drivers side gasket.

Also You need to turn it so the door opens in a workable way as it is hinged on the left side.

It will work with only a small amount of grunt work, mine is still a bare shell so it won't be too difficult.
