I even got a little aggresive twisting on them and they seem to be fine.  kinda surprises me too.  the car only has 52,000, but its always been a garage queen. 
in that "black air" documentry, they showed the last grand national made that has spent its life in a bedroom of a house.  when they rolled it out for some footage, the fillers looked like they where cloudy just like mine, lol!
I have heard nothing but great reviews about spoolfools fillers.  actually just talked to another member local today that just saw them at bowling green and was very impressed.
Unfortunetly I don't want fiberglass  

   I want the factory style plastiky ones.
I'll report back with my results
