MGA door panel felts

["Howard Battan" <battanhr@comcast.net>]

Hi all. I am working on my '57 MGA - putting the finishing touches on the
doors. In the past, there were felt/horsehair-type packing strips between
the inner frame braces and the aluminum door material. I've looked at the
Moss catalog, but haven't found them. Anybody know a source for the material
suitable for their replacement?

TIA
