Lead?! Why would anyone want to use lead for a sound barrier on the D or any car for that fact!! You know how much weight you would add to the car? That would cause the car to have LESS performance (slower, crappy gas milege..etc) which is something you don't want. You could also damage your engine and/or tranny with the added weight by making them work harder than they should be. Use neoprene mats, you can easily find sound deading material at any good audio store..I found that PC Richards is selling them (NY area at least). They use the mats in the doors and trunks of cars to sound proof it so that the stereo sound will be greater and resonate in the car...no sound escaping from INSIDE the car. They also have Rubberized undercoating for the car that is a sound deading material. You simply spray it on the underside of the car. Although you might be able to lift the carpeting in the D and spray it on the inside floor, you won't see it after the rug is put back and it won't cause any headaches if you need to do some repairs under the car (stuff gets everywhere). Most Auto manufactures use this stuff to minimize the road noise (look under you other cars besides the D, it's the black rubbery stuff that has a wrinkle finish to it). The Draw back is that it is messy, if you are doing it yourself, and not as good as the mat...but if you use it in conjunction with the mat, it may decrease the road noise considerably.
