Bill your interior changes look very good...I am half way into a interior change but am undecided on whether to amke major changes. I have elminated the rear rubber mats and padding and used Quiet Car a water based sound deadner. I used a foil backed carpet pad that is extremely light and reflects heat. I would like to eliminate the rear seat but would like more information on how the carpet fits. Did you use any glue for this or just tacked the carpet? I think the carpet replacement will fit over the new padding without additional backing for depth.
