I lined the floors under the seats, the rear deck, both horizontal and
vertical panels, and part of the tranny tunnel with this stuff nearly 5
years ago. I just pulled on of the seats yesterday and the Dynamat is mashed
where the seat rails were. The rest of it is in good shape. And it made a
whale of a difference in the sound inside the car. My major worry - I might
not be able to hear a problem in the diff. Well I did when it went, but then
again you could hear it for blocks!!

I am redoing the carpets soon and I will likely add more to the floor.

Larry's suggestion of just adding a bit to the doors is interesting. Seems
it would deaden vibration, but not block sound.
