I have a brand new carpet kit, have installed a Fat Mat product to the refurbished floor basically under where all the carpet lies. I have a roll of jute type backing to place under the carpet as required. I cannot recall which pieces are glued direct to the body and which pieces had carpet backing. The attached schematic shows all the individual pieces and install locations. I need advice as to how to proceed with the jute material as I am sure some pieces do not need this????
