OEM a sound isolation in the trunk?

[torbsim]

Did the original 1973 Mustang Mach 1 have sound insulation glued into the trunk over the gray mottled paint, or was the mat “only” standard?

I never remembered any glued anything. Just the grey material you mentioned.

Thank you very much! I have soundproofing here, but it's not original. Then I don't want to install it.

The vinyl trunk mat did not have any insulation from the factory as far as I know. If you are concerned with noise or insulation, you can add sound deadener under the trunk floor. It wouldn't be an issue, unless your car is a concourse numbers match car, and is being judged as such. I believe our cars had insulation under the trunk floor for the fuel tank already. I installed a sound deadener pad under the trunk floor between the floor and the fuel tank. I don't know if it is correct for the car, but I thought it was and your car may already have it. I bought it from NPD I think, and it was listed for that specific purpose so I thought it was correct for the car. Either way, I think it is a good idea to insulate the tank from the body if it isn't already there, I welded in a new trunk floor so I had nothing there at first.

Think splatter paint. The light gray version was used in our cars' trunks from the factory.
