I have tackled the interior of my '64 coupe and have removed all of the carpeting, underlayment and dash. I have removed all of the residual glue(which was good stuff to last this long). In doing a search, there is Al Knoch vs ACC for carpeting. I have not found a specific source for the underlayment like the original that had a fiber material that was glued to the floor and a rubber backing. All vendors indicated there was no insulation under 63 & 64 Corvettes which I find unusual since I tore this stuff out of the car. I am aware of Dynamat products and the like. My interest is in trying to keep things essentially original but the underlayment will not be seen. As far as noise and heat issues, I don't have a concern since this is not going to be a long distance cruiser Has factory air and Chevrolet side exhaust). I have read where DUB uses Dynamat and Dynapad in some of his restorations. What was used originally under the carpet of a '64 Vette, where can it be bought, how does the thickness of a Dynamat and Dynapad combination compare with the original (I can see that the edges of the mat may have to be beveled and trimmed in the areas of the center console and edges next to the door sill). What have been the experiences of you all regarding the carpeting vendor for 63-64 Vettes that are not the molded carpets as far as fit and finish? Thank you all in advance.

 

I am aware of the black material that was shaped to fit certain areas of the floor. I cannot remember specifically if it was used on a 1964 due to I generally do not worry about that due to most people are more worried about an upgrade in materials used to provide an added benefit. I do know that the carpet for a 1964 already had a foam padding made onto in and it is not the jute.

As you know I use the Dynamat Extreme and the DynaPad and when I use them I have never had any issues in the carpet fitting. Sometimes i may need to remove the jute that was glued on the back of the carpet ...sometimes do not have to.

The thickness of these two materials is not going to throw off how the carpet fits due it it is not super precise from the get-go. I would think that the factory stuff when compressed is about 1/8"+/- and both layers of the Dynamat stuff may slightly around 3/16" compressed... if that.

I use Al Knoch carpet due to he makes it and I have seen the difference in how well it is made versus ACC.

If you are not worried about heat or noise....then whatever you choose to sue is up to you.

DUB:
I followed up on your Dynamat Extreme and Dynapad. The Dynapad is not pre-cut and comes in bulk. How many square feet do you order for a C2 coupe and do you use 3M 90 adhesive? I imagine it is just cut to fit with a patchwork in the complex curves with the Dynapad. Do you buy the pre-cut Dynamat or cut your own? If you cut your own, how much material do you buy? Thank you for your responses. .

 

Dave,

When I install the Dynamat products I cover the entire cabin area from the rear seat mounting bolts ll the way up to where the windshield is....thus doing the entire firewall.

I buy the box of 30 square feet of the Dynamat Extreme and then I believe it is three boxes of the DynaPad.

As stated...this will do from the bottom of the windshield all the way back to the rear seat bolts and to each door sill.

I will glue the DyanPad to the Extreme in certain areas but like a cross the transmission tunnel I use the glue VERY sparingly due to it is laying on top of the transmission tunnel and only needs to be bonded when it goes down each side in small areas to hold it in place.

I have a process on how I cut the DynaPad so the floor pan areas in front of the seats can be pulled out if the car gets a lot of water in it.

I use the rubber firewall plugs like GM used and some glue to hold the DynaPAd onto the firewall vertical areas and then also use some gaffers tape to cover any seams that meet up to make it look good also. ( if needed depending on how well the pieces come together visually).

Dave, I also have a '64 that is very original. My interior carpet was replaced about three years ago by the previous owner, but he left all of the jute and rubber to mat in tact. If you took yours out, why not use it as a template for new material, or order just the jute under mat and glue it to the original rubber top mat? You can buy the jute precut for your entire interior. This is of course if you want to stay as original.

 

You have a good idea but I threw my old stuff out. There were areas that the carpet and pad were worn through.
