Asbestos in A bodies?

Hi guys.
Quick question. Do any of you know whether the insulation on the floorpan under the factory vinyl for 1971 year Valiants had asbestos in it? What is this stuff? It kind of reminds me of coconut fiber. Did any of them for any year use asbestos in the floorpan insulation?

I'm in the process of ripping my flooring out to replace with new and I want to know if I should dispose of all that insulation special or not.

Thanks!
