Hi guys , girls , I have a 911 922 , the door card fixtures have changed from the previous model , I'm trying to get the door lining soundproofed with dynamatt , to date no one in the industry locally have removed the door car , Porsche dealers will not share where the new fixing screw is located or a pdf of the fixings complete , iv had 2 companies check it out and neither can find the new fixing points and also don't want to medal too much , can anyone help with this please , thanks stuart
