I have a couple questions on interior removal on a '00 GT conv. The car sat for 4 years and stinks badly so I gutted the entire interior aside from firewall insulation, I dont know how it comes out, so that's my first question. My second is I plan to spray rust reformer, butyl pads, then insulation pads for the floor pans (no jute), can I do the same behind the dash and firewall? Lastly there seems to be a piece of cardboard under the pedals beneath the firewall insulation, what is this and should it be replaced? Thank you for any help
