Sound insulation

["Vito Pacione" <vito@argohouston.com>]

Does anyone know where to get sheets of the original-like sound deadening
sheets that Triumph used? Looking for a source here in the states. It was used
under the carpets in some areas as well as in the doors.

It was a self adhesive tar based material. NOT dynamat and not any felt based
material.

Thanks!
