I cut into the headliner in the area where the roof will be cut out. I had to remove 2 wire supports and some of the glued on insulation. I should have worn a dust mask, the fibrous insulation is a bit dusty. Be sure to leave a good amount of uncut headliner at the perimeter so you have lots to play with when finishing the cut edges of the hole. Looks like I am going to make that hole tomorrow.

That old foam in your second photo is gooey nasty stuff. Make sure not to get it on anything as it stains and is impossible to get off. There is more of that stuff under the front section too.

Yes, it was sticky and nasty. And it was sealing up the box section/vent to roof joint, ugh.
