Is there asbestos in this brown firewall pad for mopar a bodies?

Only way for you to know for sure is to have YOUR samples tested.

If you do not want to go through the testing process there are ways to remove it like the pros do that would be safer. but I would say if you have been driving the car or one of the same age for any number of years and it does contain asbestos you have gotten more in your body then you will get in by doing a damp removal with proper respirators etc.

If you do get it tested ( which is not all that expensive by the way) let us know what you find
