Padding under the carpet?

[Matti Roth]

I would appreciate any info where to put those loose padding pieces under the carpet. 4  big ones are quite simple but how about those smaller triangular parts?

and where shall those long black pieces go? They are like carton with some kind of treatment

The padding is just to level the floor off. The metal pan is full of dips and grooves, so just fill them in to make the floor level.

If this is original padding I would toss it and get some newer aftermarket fire resistant padding. I know of more than one car where the exhaust caught this stuff on fire where it burned the exposed padding under the driver side where floor board was compromised. I actually use this stuff as fire starter in my old cook house! While I like staying original as I can, there is much better material out there now that is fire resistant and provide better sound proofing.

Thanks for good reminder! I plan to put some sound deadening material to floor to resist heat as well.

Two long pieces go under the rear seat where is no carpet. Pieces have holes in place where rear seat belts are attached.

Padding pieces found their own places. They level the floor off like Russ mentioned.

Is there another material you guy think these leveling panels could be made of? Getting ready to put new carpet in and I dont have these panels anymore. Body shop threw them away
