I'll make sure I'm not sitting in the truck when I turn the a/c on

I covered the dash as best I could, there might be some dust left over, but I'm not that worried about it. This truck was sunk in mud and water so deep it was up to the center console. If I end up with no smell (which it seems I have already), and a little walnut shell dust, the truck will be in better shape than before the fire! The dash already is cleaner than it has been in three years!
At least I'm not concerned about the smell anymore - I have that under control. The only thing I'm really nervous about is doing the head liner and finishing up welding the fender wells. This truck is going into 2011 as a better truck with a better interior than it did going into 2010!
