This a good price and I think it's due to some bad reviews. I have this on the floor of the '66 and it hasn't created any problems in 2 years. The bad reviews are more recent and may reflect a bad batch or lower quality. I wouldn't recommend it for any area other than the floor. It's too heavy to hang inside doors or stay on the roof.

So Mitch, would it be worth the price and effort to install it in a Non-AC 66? Does it quite up the car at all? I currently have the original style insulation on the back of the carpet.

I think my '66 is quiet inside. It didn't have any interior the 12 miles I drove it when I first got it, so anything would seem better...

I don't notice any heat from the floor either, like I do in my Camaro with just carpet.

Some of the reviews are strongly negative. Mitch have you ever lifted your carpet to take a peak and see how it’s holding up?

Could very well be a good product at a good price, I would think two boxes would do an A body car.

Jim, quality soundproofing makes a big, big difference, it did in the Elky.

I’ve often wondered, what’s to prevent a competitor from writing nasty reviews and slamming the competitions product on their own web site when their prices get to low and start cutting into their sales?

Last spring, I removed the front carpet to change the shifter bezel and put in new carpet. There was nothing like what the others describe going on, even right under the header collectors. I was surprised to read the bad reviews, but maybe there was a bad batch or it is corporate sabotage, like you bring up.

Eastwood sells an add-on kit too for much less than the full kit and it was plenty to cover the entire floor. Without the ad-on, I had left the floor bare under the front seats in order to cover the floor under the rear seat area. I covered the bare spot when I had the carpet out last spring. I still have another complete box and some of the add-on here that I will put in my '38 this year.

As a side note, if you buy the insulation, don't buy the cheap $10 roller. It is junk. I had to "modify" mine after just a short time to keep the roller from falling out of the handle. Get a good roller.

My Car has the original, kind of cardboard insulation on the roof. It has some replacement insulation and some original insulation on the firewall toeboard area. There never was any inslulation behind the door panels, and just a kind of fiberglass-mat layer between the rear seat and in front of the trunk divider board. I wonder if just as much noice is coming from those areas as well as some from the floor. So wondering if sound-proofing the floor will do any thing.

Covering the floor cuts down on road noise and exhaust heat in the interior. I replaced both doors on the '66 too and sprayed NAPA undercoating on the inside of the outer skins to reduce noise and vibration. The repop door skins would flex easily because they are thinner. The undercoating eliminated that.

I used dound deadener on my 72 a couple winters back. Made a huge difference in the interior sound level, now I hear the other stuff.

As for the roller, I bought a small linoleum roller from the hardware store. Might be 3" wide or so, worked very well. I did mine in the winter. Though a heater was on and took the nip out of the air, the metal was still a little cold, so I pre-heated the floor section I was doing with a heat gun and then after applying the deadener, I used the gun again to make it a little more pliable and pressed it onto the panel for the best adhesion.

Sorry this is an old thread have an install question. I removed all the tar paper like card board stuff in on the floor and thinking getting this stuff.
Do you put the original carpet mat back in over this stuff or does this product eliminate the need of putting in the bulky carpet mat ?
To add it Looks like my carpeting has some back matting on it already.

The mat is on the carpet and goes back with it. The sound deadener replaces the tar paper from the factory.
