1969 Pontiac Interior Restoration: Any Asbestos?

Hi.

I have a 1969 Pontiac LeMans convertible that needs some
work, especially the interior. When removing the back bench
seat, I see that the inside is stuffed with some kind of material
that looks like loose attic insulation. It is very soft and fluffy,
and the color is a cross between gray, white and tan, but looks
like it was probably white when new. Feels like a wad of cotton.
It seems to be the original factory material.

Any chance that this could contain asbestos? I tried to burn a
handful of this stuff, and the outer layer flamed briefly, but it
would not catch fire. Does anyone know what GM was stuffing
their seats with back in '69? Could there be asbestos anywhere
else in the car's interior? I definitely want to find out before I
begin restoration. I called Pontiac's vintage division and the guy
told me that he was not aware of any asbestos in the interior,
but he didn't sound very sure.

Thanks for your help.
