Hurricane Hinge cutting question

Hey all,
Im getting ready to cut the Hinge after pouring over the Sticky on the subject for the last 2 days. I’m going to take a guess that I have to remove the material listed below so the Hatch side will fit within the walls? That’s taking into account the 1/2" + on either side for the Roof side of the hinge, and the 1/4" for the hatch side per MJ's explicit instructions in the Sticky,
Any help would be greatly appreciated....no really
Anyone, Anyone?
Thanks,
Mike
