vent box, park brake and brake peddle assembly. Unless you slice things to slip over the cable and behind the box.. I have seen them put in in pieces but it is so much easier and a nicer job to just take it apart and paint behind everything first
I agree aboout removing everything there is a section that i used spray adhesive to glue the insulation on. I do beleive the factory did it the same way on the underside of the cowl.
