Removing the vent window and drilling the mounting holes is not major surgery. All it takes is a couple wrenches, a screwdriver and a drill. A little patience to make sure you get the window fit and drill the mounting holes in the right spot.
No welding, no cutting- it's not major surgery. Is it probably easier to find a duster/demon door? Sure, it probably is in a lot of places. But it's definitely not major surgery. I'll post the pictures of the door frames I have tomorrow, you'll see what I mean.
