I've got a 110 hard-top and used a big roll of 19mm thick Armaflex (industrial pipe lagging) bought off fleabay. Cut into sections to fit between box sections on the roof and spay glue on, I then used foil covered bubble wrap (B&Q) and covered the whole roof, aluminium taped the joins and hey presto a nice tidy shiny, bling headlining. The sides were filled with Armaflex off-cuts and camping mat, then paneled the sides with acoustic carpet covered 6mm plywood and self tapped screwed it on, Rubber matting on load-bed and wheel boxes. This transformed a cold, condensation covered, noisy tractor into a comfortable 4x4
