Take a chisel bit on an air hammer and it will pop right off. (Or you can do it by hand with a hammer and chisel) Then finish by lightly sanding remaining residue and glue on a flat belt sander. You should use a good dust mask. I normally bead blast, then paint to keep them from rusting... before riveting the woven linings on. You will get an excellent job if you follow this procedure. I have plenty of NOS Ford linings and rivets if you haven't bought them yet.
