What to use for under carpet?

you guys rok...I am going to basically do what Davis did and except maybe use dynamat to keep things quiet

I spent most of last winter putting Dynamat EVERWHERE on the interior except for the roof. The headliner on my 73 is original and in perfect condition and I didn't want to try to remove and replace.

Under the carpets and seats I also installed Dynapad over the Dynamat. This product must be glued down but is soft and makes a perfect pad for carpet.

I stripped the old tar from the transmission tunnel (used adhesive remover which worked well), installed Dynamat and then 1/4" Dynaliner. This extra step really made a big difference in trans tunnel temp and is highly recommended. Reinstalling the original vinyl was difficult but now looks like it was never removed.

It took about 15 hrs. each for the doors, including both sides of the inner panel. Originally I didn't think that I could get to the surfaces without removing the window but with patience I was able to cover most of it. The insides of my arms was bruised for weeks from pressing Dynamat on the inside of the inner panel.

Don't forget to put Dynamat inside of the plastic interior panels, it really stiffens them. I used a small square of dynamat between the panels and the mounts, then made holes for the rivets with an awl. This eliminated all the squeaking.

Tip: I bought all of my Dynamat from Amazon.com which was half the price of my local Best Buy. You will use more than you think and I estimate that I have over 50 pounds installed.

This is a very time consuming project but you will really appreciate the difference.

Cheapest place I found the bulkpacks is eBay. And yes, putting it on the doors makes a huge difference. You don't need to cover them completely just try and get as much as possible.
