I try to get it of the rotisserie as soon as possible as it much easier to reassemble on the lift. So I get the fiberglass tub back in and glue in 1″ think high density closed cell foam between the fiberglass and floorpan to cut noise. Ferrari had nothing in between and used tar paper on the top of the fiberglass. So yes this is an improvement that is not visible. I also replaced the fiberglass bottom with aluminum. Hopefully I won’t get a nasty email over this. They switched from fiberglass to aluminum sometime during the 72 production. So now it’s on the lift and I can start reassemble. I usually start in the front where most of the work is and work towards the rear.
